TLE9263QX system features data sheet 25 rev. 1.1, 2014-09-26 5.1.2 sbc normal mode the sbc normal mode is the standard operating mode fo r the sbc. all configurations have to be done in sbc normal mode before entering a low-power mode (see also chapter 5.1.6 for the device configuration defining the fail-safe mode behavior) . a wake-up event on can, linx and wkx will create an interrupt on pin int - however, no change of the sbc mode will occur. the configuration options are listed below: ? vcc1 is active ? vcc2 can be switched on or off (default = off) ? vcc3 is configurable (off coming from sbc init mode ; as previously programmed coming from sbc restart mode) ? can is configurable (off coming from sbc init mode ; off or wake capable coming from sbc restart mode, see also chapter 5.1.5 ) ? lin is configurable (off coming fr om sbc init mode; off or wake capable coming from sbc restart mode, see also chapter 5.1.5 ) ? hs outputs can be switched on or off (default = off) or can be controlled by pwm; hs outputs are off coming from sbc restart mode ? wake pins show the input level and can be selected to be wake capable (interrupt) ? cyclic sense can be configured wit h hs1...4 and timer1 or timer 2 ? cyclic wake can be configured with timer1 or timer2 ? watchdog is configurable ? all fox outputs are off by default. coming from sbc rest art mode fox can be active (due to a failure event, e.g. watchdog trigger failure, vcc1 short circ uit, etc.) or inactive (no failure occurred) in sbc normal mode, there is the possibilit y of testing the fo outputs, i.e. to verify if setting the fo pin to low will create the intended behavior within the system. the fo ou tput can be enabled and then disabled again by the microcontroller by setting the fo_on spi bit. this feature is only intended for testing purposes.
TLE9263QX system features data sheet 26 rev. 1.1, 2014-09-26 5.1.3 sbc stop mode the sbc stop mode is the first level technique to reduc e the overall current consumption by setting the voltage regulators vcc1, vcc2 and vcc3 into a low-power mode. in this mode vcc1 is still active and supplying the microcontroller, which can enter a power down mode. t he vcc2 supply, can & lin mode as well as the hsx outputs can be configured to stay enab led. all kind of settings have to be done before entering sbc stop mode. in sbc stop mode any kind of spi write commands are ignored and the spi_fail bit is set, except for changing to sbc normal mode, triggering a sbc soft reset, refreshing the watchdog as well as for reading and clearing the spi status registers. a wake-up event on can, linx and wkx will create an interrupt on pin int - however, no change of the sbc mode will occur. the configuration options are listed below: ? vcc1 is on ? vcc2 is fixed as configured in sbc normal mode ? vcc3 is fixed as configured in sbc normal mode ? can mode is fixed as configured in sbc normal mode ? lin mode is fixed as configured in sbc normal mode ? wk pins are fixed as configured in sbc normal mode ? hs outputs are fixed as configured in sbc normal mode ? cyclic sense is fixed as c onfigured in sbc normal mode ? cyclic wake is fixed as co nfigured in sbc normal mode ? watchdog is fixed as configured in sbc normal mode ? sbc soft reset can be triggered ? fox outputs are fixed, i.e. the stat e from sbc normal mode is maintained an interrupt is triggered on the pin int when sbc stop mo de is entered and not all wake source signalization flags from wk_stat_1 and wk_stat_2 were cleared. note: if switches are enabled during sbc stop mode, e.g. hsx on with or without pwm, then the sbc current consumption will increase (see chapter 4.4 ). note: it is not possible to switch di rectly from sbc stop m ode to sbc sleep mode. do ing so will also set the spi_fail flag and will bring the sbc into restart mode. note: when wk1 and wk2 are configured fo r the alternate measurement function ( wk_meas = 1) then the wake inputs cannot be selected as wake input sources.
TLE9263QX system features data sheet 27 rev. 1.1, 2014-09-26 5.1.4 sbc sleep mode the sbc sleep mode is the second level technique to reduce the overall current consumption to a minimum needed to react on wake-up events or for the sbc to perfor m autonomous actions (e.g. cyclic sense). in this mode, vcc1 is off and not supplying the microcontroller anymor e.the vcc2 supply as well as the hsx outputs can be configured to stay enabled. the setti ngs have to be done before entering sbc sleep mode. a wake-up event on can, linx or wkx will bring the device via sbc restar t mode into sbc normal mode again and signal the wake source. the configuration options are listed below: ? vcc1 is off ? vcc2 is fixed as configured in sbc normal mode ? vcc3 is fixed or off as configured in sbc normal mode ? can mode changes automatically from on or receive on ly mode to wake capable mode or can be selected to be off ? lin mode changes automatically from on or receive only mode to wake capable mode or can be selected to be off ? wk pins are fixed as configured in sbc normal mode ? hs outputs are fixed as configured in sbc normal mode ? cyclic sense is fixed as c onfigured in sbc normal mode ? cyclic wake is not available ? watchdog is off ? fox outputs are fixed, i.e. the stat e from sbc normal mode is maintained ? as vcc1 is off during sbc sleep mode, no spi communication is possible; ? the sleep mode entry is signalled in the spi register dev_stat with the bit dev_stat it is not possible to switch all wake source s off in sbc sleep mode. doing so will set the spi_fail flag and will bring the sbc into sbc restart mode. in order to enter sbc sleep mode successfully , all wake source signalization flags from wk_stat_1 and wk_stat_2 need to be cleared. a failure to do so will result in an immediate wake-u p from sbc sleep mode by going via sbc restart to normal mode. all settings must be done before entering sbc sleep mode. note: if switches are enabled during sbc sleep mode, e.g. hsx on with or without pwm, then the sbc current consumption will increase (see chapter 4.4 ). note: cyclic sense function will not work properly anymore in case of an over current, over temper ature, under- or overvoltage (in case function is se lected) event because the respecti ve hs switch will be disabled. note: when wk1 and wk2 are configured fo r the alternate measurement function ( wk_meas = 1) then the wake inputs cannot be selected as wake input sources.
TLE9263QX system features data sheet 28 rev. 1.1, 2014-09-26 5.1.5 sbc restart mode there are multiple reasons to enter the sbc restart mode . the purpose of the sbc rest art mode is to reset the microcontroller: ? in case of under voltage on vcc1 in sbc normal and in sbc stop mode, ? in case of over voltage on vcc1 if the bit vcc1_ov_rst is set and if cfgp = ?1?, ? due to 1st incorrect watchdog triggering (only if confi g1, config3 or config 4 is selected, otherwise sbc fail- safe mode is immediately entered), ? in case of a wake event from sbc sleep or sbc fail-safe mode or a release of over temperature shutdown (tsd2) out of sbc fail-safe mode this transition is used to ramp up vcc1 after a wake in a defined way. from sbc restart mode, the sbc goes au tomatically to sbc normal mode, i.e the mode is left automatically by the sbc without any microcon troller influence. the sbc mode bits are cleared. as shown in figure 48 the reset output (ro) is pulled low when entering restart mode and is released at the transiti on to normal mode after the reset delay time ( t rd1 ). the watchdog timer will start with a long open wi ndow starting from th e moment of the rising edge of ro and the watchdog per iod setting in the register wd_ctrl will be changed to the respective default value ?100?. leaving the sbc restart mode will not result in ch anging / deactivating the fail outputs. the behavior of the blocks is listed below: ? all fox outputs are activated in case of a 1st watchdog trigger failure (if config1 or config2 is selected) or in case of vcc1 over voltage detection (if vcc1_ov_rst is set) ? vcc1 is on or ramping up ? vcc2 will be disabled if it was activated before ? vcc3 is fixed or ramping as configured in sbc normal mode ? can is ?woken? due to a wake event or off depending on previous sbc and transceiver mode (see also chapter 10 ). it is wake capable when it wa s in can normal-, receive only or wake capable mode before sbc restart mode ? lin is ?woken? or off depending on prev ious sbc and transceiver mode (see also chapter 11 ). it is wake capable when it was in lin normal-, receive on ly or wake capable mode before sbc restart mode. ? hs outputs will be disabled if they were activated before ? ro is pulled low during sbc restart mode ? spi communication is ignored by th e sbc, i.e. it is not interpreted ? the restart mode entry is signalled in the spi register dev_stat with the bits dev_stat table 7 reasons for restart - state of spi status bits after return to normal mode prev. sbc mode event dev_stat wd_fail vcc1_uv vcc1_ov vcc1_sc normal 1x watchdog failure 01 01 x x x normal 2x watchdog failure 01 10 x x x normal vcc1 under voltage reset 01 xx 1 x x normal vcc1 over voltage reset 01 xx x 1 x stop 1x watchdog failure 01 01 x x x stop 2x watchdog failure 01 10 x x x stop vcc1 under voltage reset 01 xx 1 x x stop vcc1 over voltage reset 01 xx x 1 x sleep wake-up event 10 xx x x x fail-safe wake-up event 01 see ?reasons for fail safe, table 8 ?
TLE9263QX system features data sheet 29 rev. 1.1, 2014-09-26 note: an over voltage event on vcc1 will only lead to sbc rest art mode if the bit vcc1 _ov_rst is set and if cfgp = ?1? (config 1/3). note: the content of the wd_fail bits will depend on the devic e configuration, e.g. 1 or 2 watchdog failures. 5.1.6 sbc fail-safe mode the purpose of this mode is to bring the system in a safe status after a failure condition by turning off the vcc1 supply and powering off the microcontroller. after a wa ke event the system is then able to restart again. the fail-safe mode is automatically reached for following events: ? after an sbc thermal shutdown (tsd2) (see also chapter 15.9.3 ), ? in case of over voltage on vcc1 if the bit vcc1_ov_rst is set and if cfgp = ?0?, ? after a 1st incorrect watchdog trigger in config2 ( cfg = 1) and after a 2nd incorrect watchdog trigger in config4 ( cfg = 0) (see also chapter 5.1.1 ), ? if vcc1 is shorted to gnd (see also chapter 15.7 ), ? after 4 consecutive vcc1 unde r voltage events (only if vs > v s,uv , see chapter 15.6 ). in this case, the default wake sources (can, linx, wk 1...3, see also registers wk_ctrl_2 , bus_ctrl_1 and bus_ctrl_2 ) are activated, the wake events are cleared in the register wk_stat_1 , and all output drivers and all voltage regulators are switched off. when wk1 and wk 2 are configured for the al ternate measurement function ( wk_meas = 1) then wk1 and wk2 will stay configured for the measurement fu nction when sbc fail-safe mode is entered, i.e. they will not be activated as wake sources. the sbc fail-safe mode will be maintained until a wake event on the default wake sources occurs. to avoid any fast toggling behavior a filter time of typ. 100ms ( t fs,min ) is implemented. wake ev ents during this time will be stored and will automatically l ead to entering sbc restart mode after the filter time. in case of an vcc1 over temperatur e shutdown (tsd2) the sbc restart mo de will be reached au tomatically after a filter time of typ. 1s ( t tsd2 ) without the need of a wake event. leaving the sbc fail-safe mode will not result in deactivati on of the fail output pins. the following functions are influenced during sbc fail-safe mode: ? all fox outputs are activated (see also chapter 14 ) ? vcc1 is off ? vcc2 is off ? vcc3 is off ? can is wake capable ? linx is wake capable ? hs outputs are off ? wk pins are wake capable through static sense (with default 16s filter time) ? cyclic sense and cyclic wake is disabled ? spi communication is disabled because vcc1 is off ? the fail-safe mode activation is signalled in the spi register dev_stat with the bits failure and dev_stat
TLE9263QX system features data sheet 30 rev. 1.1, 2014-09-26 note: an over voltage event on vcc1 will only lead to sbc fail-safe mode if the bit vcc1_ov_rst is set and if cfgp = ?0? (config 2/4). note: the content of the wd_fail bits will depend on the devic e configuration, e.g. 1 or 2 watchdog failures. note: see chapter 15.6.1 for detailed description of the 4x vcc1 under voltage behavior. 5.1.7 sbc development mode the sbc development mode is used during the developme nt phase of the module. it is especially useful for software development. compared to the default sbc user mode operation, this mode is a super set of the state machin e. the device will start also in sbc init mode and it is possible to use all the sbc modes and functions with following differences: ? watchdog is stopped and does not need to be triggered. therefore no reset is triggered due to watchdog failure ? sbc fail-safe and sbc restart mode are not reached du e to watchdog failure but the other reasons to enter these modes are still valid ? linx, can and vcc2 default value in sbc init mo de and entering sbc normal mode from sbc init mode is on instead of off the sbc software development mode is reached automati cally if the fo3/test pin is set and kept low during sbc init mode. the voltage level moni toring is started as soon as vs > v por,f . the software development mode is configured and maintained if sbc init mode is left by sending any spi command while fo3/test is low. in case the fo3/test level will be high for longer than t test during the monitoring period then the sbc development mode is not reached . the sbc will remain in this mode for all conditions and can only be le ft by powering down the device (vs < v por,f ). table 8 reasons for fail-safe - state of spi status bits after return to normal mode prev. sbc mode failure event dev_ stat tsd2 wd_ fail vcc1_ uv vcc1_ uv_fs vcc1_ ov vcc1_ sc normal 1 x watchdog failure 01 x 01 x x x x normal 2 x watchdog failure 01 x 10 x x x x normal tsd2 01 1 xx x x x x normal vcc1 short to gnd 01 x xx 1 x x 1 normal 4x vcc1 uv 01 x xx 1 1 x x normal vcc1 over voltage 01 x xx x x 1 x stop 1 x watchdog failure 01 x 01 x x x x stop 2 x watchdog failure 01 x 10 x x x x stop tsd2 01 1 xx x x x x stop vcc1 short to gnd 01 x xx 1 x x 1 stop 4x vcc1 uv 01 x xx 1 1 x x stop vcc1 over voltage 01 x xx x x 1 x

TLE9263QX system features data sheet 32 rev. 1.1, 2014-09-26 5.2.1.1 configuration and op eration of cyclic sense the correct sequence to configure the cyclic sense is shown in figure 6 . all the configurations have to be performed before the on-time is set in the timerx_ctrl registers. the sett ings ?off / low? and ?off / high? define the voltage level of the respective hs driver be fore the start of the cyclic sense. the intention of this selection is to avoid an unintentional wake due to a voltage level change at the start of the cyclic sense. cyclic sense (=timerx) will start as so on as the respective on- time has been selected independently from the assignment of the hs and filter co nfiguration. the selection of the respective timer (config c/d see chapter 12.2.1 ) must therefore be done before starting the ti mer. the correct configuration sequence is as follows: ? configure the initial level ? mapping of a timer to the respective hsx outputs ? configuring the respective filter timing and wk pins ? configuring the timer period and on-time figure 6 cyclic sense: configuration and sequence note: all configurations of period and on-time can be se lected. however, recommended on-times for cyclic sense are 0.1ms, 0.3ms and 1ms. the sp i_fail will be set if the on-tim e is longer than the period. cyclic sense configuration assign timer to selected hs switch in hs_ctrl_x enable wkx as wake source with configured timer in wk_flt_ctrl cyclic sense starts / ends by setting / clearing on-time timer1, timer2 select timer period and desired on-time in timerx_ctrl wk1, wk2, wk3 with above selected timer period : 10, 20, 50, 100, 200ms, 1s, 2s on-time: 0.1, 0.3, 1.0, 10, 20ms assign timerx_on to off/low or off/high in timerx_ctrl timer1, timer2 select wkx pull-up / pull-down configuration in wk_pupd_ctrl no pull -up/-down, pull -down or pull -up selected, automatic switching changing the settings can be done on the fly, changes become effective at the next on-time or period
TLE9263QX system features data sheet 33 rev. 1.1, 2014-09-26 the first sample of the wk input value (high or low) is taken as the reference for the next cycle. a change of the wk input value between the first and second cycle recognized duri ng the on-time of the second cycle will cause a wake from sbc sleep mode or an interrupt during sbc normal or sbc stop mode. a filter time of 16s is implemented to avoid a parasitic wake-up due to tran sients or emc disturbances. the filter time t fwk1 is triggered right at the end of the selected on-time and a wake signal is recognized if: ? the input level will not cross the switchi ng threshold level of typ. 3v during th e selected filter time (i.e. if the signal will keep the high or low level) and ? there was an input level change betw een the current and previous cycle

data sheet 49 rev. 1.1, 2014-09-26 TLE9263QX external voltage regulator 3 8.2 functional description the external voltage regulator can be used as an independent voltage regulator or in load-sharing mode with vcc1. setting vcc3_on in the m_s_ctrl register in sbc normal mode sets the stand-alone configuration of vcc3 as an independent voltage regulator. the lo ad sharing configuration is set via the spi bit vcc3_ls in the hw_ctrl register. figure 18 selecting the configuration of the vcc3 regulator depending on the configur ation the regulator will act in the re spective sbc mode as described in table 12 . after the vcc3 configuration has been select ed, it cannot be changed anymore. in stand-alone configuration the maximum current i cc3max is defined by the current limitation determined by the used shunt. in load sharing configuration, the shunt is used to determine the current ratio between vcc1 and vcc3. since the junction temperature of the external pnp transist or cannot be sensed by the sbc, it cannot be protected against over temperature by the sbc. theref ore the thermal behavior has to be analyzed by the application. for low-quiescent current reasons, the output voltage to lerance is decreased in sbc stop mode because a low- power mode regulator with a lower accu racy will be active for small loads. if the base current on vcc3 exceeds i vcc3base > i vcc3base,ipeak,r then the high-power mode regulator is enabled additionally to support an optimum dynamic load behavior. if the base current on vcc3 falls below the threshold ( i vcc3base < i vcc3base,ipeak,f ), then the low-quiescent current consumption is resumed again by disabling the high-power mode regulator. only the high-power mode regulator is active in sbc normal mode. the status of vcc3 is reported in the sup_stat_2 spi register. the regulator w ill switch off in case of vs dropping below vs_uv regardless of the vcc3 c onfiguration and will be auto matically enabled again when exceeding this threshold voltage unless the control bit vcc3_vs_ uv_off is set. vcc3 will also stay active in sbc stop mode when the bit vcc3_ls_ stp_on is set and when load sharing is configured (for detailed protection features see chapter 15.7 and chapter 16.3 ). set bit vcc3_v_cfg = 0 set bit vcc3_on = 0 or 1 set bit vcc3_ls = 1 vcc3_v_cfg is automatically set to 0 vcc3_ls, vcc3_on and vcc3_v_cfg cannot be changed anymore vcc3_ls and vcc3_v_cfg cannot be changed anymore (once vcc3_on is set for the first time ) vcc3 load sharing? default value of vcc3_ls = ?0' vcc3 output voltage in stand-alone configuration set bit vcc3_v_cfg = 1 set bit vcc3_on = 0 or 1 stand-alone configuration vcc3 = 5v stand-alone configuration vcc3 = 3.3v vcc3 load sharing vcc3 = vcc1 no yes 5.0v 3.3v
data sheet 50 rev. 1.1, 2014-09-26 TLE9263QX external voltage regulator 3 note: the configuration of the vcc3 voltage regulator behavior must be done immediately after power-up of the device and cannot be changed afterwards as long as the device is supplied. note: as soon as the bit vcc3_on or vcc3_ls is set for the first time, the configuration for vcc3 cannot be changed anymore. this configuration is valid - also after a sbc soft reset - as long as the sbc is powered. note: if the vcc3 output voltage is supplying external off-board loads, the application must consider the series resonance circuit built by cable inductance and decoup ling capacitor at the load. sufficient damping must be provided (e.g. a 100ohm resistor between the pnp co llector and vcc3ref with 10uf capacitor on collector - see also figure 19 ). 8.2.1 external voltage regulator as independent voltage regulator configured as an independent voltage regulator the sbc offers with vcc3 a third supply which could be used as off-board supply e.g. for sensors due to the integrated hv pins vc c3b, vcc3sh, vcc3ref. this configuration is set and locked by enabling vcc3_on while keeping vcc3_ls = 0. vcc3 can be switched on or off but the configuration cannot be changed anymore. however, the spi_fail is not set while trying to change the configuration. an over current limitation function is realized with the external shunt (see chapter 8.4 for calculating the desired shunt value) and the output cu rrent shunt voltage threshold ( v shunt_threshold ). if this threshold is reached, then icc3 is limited and only th e current limitation bit vcc3_oc is set (no other reaction) an d can be cleared via spi once the over current condition is not present anymore. if t he over current limitation feature is not needed, then connect the pins vcc3sh and vs together. in this configuration vcc3 has the under voltage signaliz ation enabled and an under voltage event is signaled with the bit vcc3_uv in the sup_stat_2 spi register. note: to avoid undesired current consumption increase of the device it must be ensured that vcc3 is not connected to vcc1 in this configuration. table 12 external voltage regulator state by sbc mode sbc mode load sharing mode 1) 1) behaves as vcc1 and has to be configured in sbc normal mode independent voltage regulator init mode off off normal mode configurable configurable stop mode off/fixed 2) 2) load sharing operation in sbc stop mode is by default disabled for power saving reasons but vcc3_ls bit will stay set. however, it can be also configured via the spi bit vcc3_ls_ stp_on to stay enabled in sbc stop mode. fixed sleep mode off fixed restart mode on or ramping fixed fail-safe mode off off

data sheet 76 rev. 1.1, 2014-09-26 TLE9263QX lin transceiver 11.2 functional description the lin bus is a single wire, bi-directional bus, used for in-vehicle networks. the lin transceivers implemented inside the TLE9263QX are the interface between the micr o controller and the physical lin bus. the digital output data from the micro controller are driven to the lin bus via the txd input pin on the TLE9263QX. the transmit data stream on the txd input is converted to a lin bus si gnal with optimized slew rate to minimize the eme level of the lin network. the rxd output sends back the info rmation from the lin bus to the micro controller. the receiver has an integrated filter network to suppress noise on the lin bus and to increase the emi (electro magnetic immunity) level of the transceiver. two logical states are possible on the lin bus according to the lin specification 2.2. every lin network consists of a master node and one or more slave nodes. to configure the TLE9263QX for master node applications, a resistor in the range of 1 k ? and a reverse diode must be connected between the lin bus and the power supply vshs. the different transceiver modes can be controlled via the spi lin1 and lin2 bits. figure 33 shows the possible transceiver mode transitions when changing the sbc mode. figure 33 lin mode control diagram 11.2.1 lin off mode the lin off mode is the default mode after power-up of th e sbc. it is available in a ll sbc modes and is intended to completely stop lin activities or when lin communication is not needed. in lin off mode, a wake-up event on the bus will be ignored. sbc normal mode sbc mode lin transceiver mode sbc stop mode sbc sleep mode sbc restart mode receive only normal mode off wake capable receive only off wake capable off woken 1 off wake capable normal mode behavior after sbc restart mode - not coming from sbc sleep mode due to a wake up of the respective transceiver : if the transceivers had been configured to normal mode, or receive only mode, then the mode will be changed to wake capable. if it was wake capable, then it will remain wake capable. if it had been off before sbc restart mode, then it will remain off. behavior in sbc development mode : lin default value in sbc init mode and entering sbc normal mode from sbc init mode is on instead of off . 1 after a wake event on lin bus sbc fail-safe mode wake capable
data sheet 77 rev. 1.1, 2014-09-26 TLE9263QX lin transceiver 11.2.2 lin normal mode the lin transceiver is enabled via spi in sbc normal mode. lin normal mode is designed for normal data transmission/reception within the lin network. the mode is available in sbc normal m ode and in sbc stop mode. transmission the signal from the microcontroller is applied to the txdlin input of the sbc. the bus driver switches the lin output stage to transfer this input signal to the lin bus line. enabling sequence the lin transceiver requires an enabling time t lin,en before a message can be sent on the bus. this means that the txdlin signal can only be pulled low after the enablin g time. if this is not ensu red, then the txdlin needs to be set back to high (=recessive) until the enabling time is completed. only the next dominant bit will be transmitted on the bus. figure 34 shows different scenarios and explanations for lin enabling. figure 34 lin transceiver enabling sequence reduced electromagnetic emission to reduce electromagnetic emissions (eme), the bus driv er controls lin slopes symme trically. the configuration of the different slopes is described in chapter 11.2.8 . reception analog lin bus signals are converted into digital signals at rxd via the differential input receiver. 11.2.3 lin receive only mode in lin receive only mode (rxd only), the driver stage is de-act ivated but reception is still possible. this mode is accessible by an spi command and is available in sbc normal and sbc stop mode. t v li n_ bus t li n, en t v txdlin t lin m ode li n no rmal li n o f f li n ,en t li n, en t recessive txd level required bevor start of tr ansmission t lin, en not ensured , no transm ission on bus cor rect sequence , bus is enabled after t lin, en t lin, en not ensured , no transm ission on bus recessive txd level required recessive dominant
data sheet 78 rev. 1.1, 2014-09-26 TLE9263QX lin transceiver 11.2.4 lin wake capable mode this mode can be used in sbc stop, sleep, restart an d normal mode by programming via spi and it is used to monitor bus activities. it is automati cally accessed in sbc fail-safe mode. a wake-up signal on the bus (filter time t > t wk,bus ) results in different behavior of the sbc, as described in below table 18 . as a signalization to the microcontroller, the rxd_lin pin is set low and will stay low until the lin transceiver is changed to any other mode. after a wake-up event the transceiver can be switched to lin normal mode for communication. rearming the transceiver for wake capability after a bus wake-up event, the transceiver is woken. however, the lin1 and lin2 transceiver mode bits will still show wake capable (=?01?) so that the rxd signal will be pulled low. there are tw o possibilities how the lin transceiver?s wake capable mode is enabled again after a wake event: ? the lin transceiver mode must be to ggled, i.e. switched to lin normal mode, lin receive only mode or lin off, before switching to li n wake capable mode again. ? rearming is done automatically when the sbc is ch anged to sbc stop, sbc sleep, or sbc fail-safe mode to ensure wake -up capability. wake-up in sbc stop and sbc normal mode in sbc stop mode, if a wake-up is detected, it is signaled by the int output and in the wk_stat_1 spi register. it is also signaled by rxdlin put to low. the same applies for the sbc normal mode. the microcontroller should set the device to sbc normal mode, there is no automati c transition to normal mode. for functional safety reasons, the watchdog will be automatically enabled in sbc stop mode after a bus wake event in case it was disabled before (if bit wd_en_ wk_bus was configured to high before). wake-up in sbc sleep mode wake-up is possible via a lin message (filter time t > t wk,bus ). the wake-up automatically transfers the sbc into the sbc restart mode and from there to normal mode the corresponding rxd pin in set to low. the microcontroller is able to detect the low signal on rxd and to read the wake source out of the wk_stat_1 register via spi. no interrupt is generated when comi ng out of sleep mode. the microcontroller can now switch the lin transceiver into lin normal mode via spi to start communication. table 18 action due to a lin bus wake-up sbc mode sbc mode after wake vcc1 int rxd normal mode normal mode on low low stop mode stop mode on low low sleep mode restart mode ramping up high low restart mode restart mode on high low fail-safe mode restart mode ramping up high low

data sheet 80 rev. 1.1, 2014-09-26 TLE9263QX lin transceiver 11.2.8 slope selection the lin transceiver offers a lin low-slope mode for 10.4 kbaud communication and a lin normal-slope mode for 20 kbaud communication. the only difference is the behavior of the transmitter. in lin low-slope mode, the transmitter uses a lower slew rate to further reduce th e eme compared to normal-slo pe mode. this complies with sae j2602 requirements.by default, the device works in lin normal-slope mode. the selection of lin low-slope mode is done by an spi bit lin_lsm and will become effective as soon as csn goes ?high?. only the lin slope is changed. the selection is a ccessible in sbc no rmal mode only. 11.2.9 flash progr amming via lin the device allows lin flash programm ing, e.g. of another li n slave with a communication of up to 115 kbaud. this feature is enabled by de-activating the slope control mechanism via a spi command (bit lin_flash) and will become effective as soon as csn goes ?high?. the spi bit ca n be set in sbc normal mode. note: it is recommended to perform flash programming only at nominal supply voltage vshs = 13.5v to ensure stable data communication.

data sheet 87 rev. 1.1, 2014-09-26 TLE9263QX wake and voltage monitoring inputs 12.2 functional description the wake input pins are edge-sensitive inputs with a switching threshold of typically 3v. this means that both transitions, high to low and low to high, result in a signalization by the sbc. the signalization occurs either in triggering the interrupt in sbc normal mode and sbc stop mode or by a wake up of the device in sbc sleep and sbc fail-safe mode. two different wake detection modes can be selected via spi: ? static sense: wk inputs are always active ? cyclic sense: wk inputs are only ac tive for a certain time period (see chapter 5.2.1 ) two different filter times of 16s or 64s can be select ed to avoid a parasitic wake-up due to transients or emc disturbances in static sense configuration. the filter time ( t fwk1 , t fwk2 ) is triggered by a level change crossing the switching threshold and a wake signal is recognized if the input level will not cross again the threshold du ring the selected filter time. figure 39 shows a typical wake-up timing and parasitic filter. figure 39 wake-up filter timing for static sense the wake-up capability for each wk pin can be enabled or disabled vi a spi command in the wk_ctrl_2 register. the wake source for a wake via a wkx pin can always be read in the register wk_stat_1 at the bits wk1_wu, wk2_wu, and wk3_wu. the actual voltage level of the wk pin (low or high ) can always be read in sbc normal and sbc stop mode in the register wk_lvl_stat . during cyclic sense, the register show the sampled levels of the respective wk pin. if fo2...3 are configured as wk inputs in its alternative function (16s static filter time), then the wake events will be signalled in the register wk_stat_2 . v wk,th t v wk t wk,f no wake event wake event v wk,th t wk,f t v int t int

data sheet 101 rev. 1.1, 2014-09-26 TLE9263QX supervision functions 15.2 watchdog function the watchdog is used to monitor the software execution of the microcontroller and to trigger a reset if the microcontroller stops serving the watchdog due to a lock up in the software. two different types of watchdog functions are implemented and can be selected via the bit wd_win : ? time-out watchdog (default value) ? window watchdog the respective watchdog functions can be selected and programmed in sbc normal mode. the configuration stays unchanged in sbc stop mode. please refer to table 26 to match the sbc modes with the respective watchdog modes. the watchdog timing is programmed via spi command. as soon as the watch dog is programmed, the timer starts with the new setting and the watchdog must be served. the watchdog is triggered by sending a valid spi-write command to the watchdog configuration register. the trigger spi command is executed when the chip select input (csn) becomes high. when coming from sbc init, sbc restart mode or in ce rtain cases from sbc stop mode, the watchdog timer is always started with a long open window. the long open window ( t lw = 200ms) allows the mi crocontroller to run its initialization sequences and then to trigger the watchdog via spi. the watchdog timer period can be sele cted via the watchdog timing bit field ( wd_timer ) and is in the range of 10 ms to 1000 ms. this setting is valid for both watchdog types. the following watchdog timer periods are available: ? wd setting 1: 10ms ? wd setting 2: 20ms ? wd setting 3: 50ms ? wd setting 4: 100ms ? wd setting 5: 200ms ? wd setting 6: 500ms ? wd setting 7: 1000ms in case of a watchdog reset, sbc restart or sbc fail- safe mode is entered according to the configuration and the spi bits wd_fail are set. once the ro goes high again the watchdog immediately starts with a long open window the sbc enters automa tically sbc normal mode. in sbc software development mode the watchdog is off and therefore no reset and interrupt are generated due to a watchdog failure. table 26 watchdog functionality by sbc modes sbc mode watchdog mode remarks init mode starts with long open window watchdog starts with long open window after ro is released normal mode wd programmable window watchdog, time-out watchdog or switched off for sbc stop mode stop mode watchdog is fixed or off sleep mode off sbc will start with lon g open window when entering sbc normal mode. restart mode off sbc will start with long open window when entering sbc normal mode.

data sheet 103 rev. 1.1, 2014-09-26 TLE9263QX supervision functions 15.2.2 window watchdog compared to the time-out watchdog the characteristic of the window watc hdog is that the watchdog timer period is divided between an closed and an open window. t he watchdog must be triggered within the open window. a correct watchdog trigger results in starting the windo w watchdog period by a closed window followed by an open window. the watchdog timer period is at the sa me time the typical trigger time and defines the middle of the open window. taking the oscillator tolera nces into account leads to a safe trigger area of: t wd x 0.72 < safe trigger area < t wd x 1.20. the typical closed window is defined to a width of 60% of the selected window watchdog timer period. taking the tolerances of the internal os cillator into account leads to the timings as defined in figure 50 . a correct watchdog service immediately resu lts in starting the next closed window. should the trigger signal meet the closed window or should the watchdog timer period elapse, then a watchdog reset is created by setting the reset output ro low and the sbc switches to sbc rest art or sbc fail-safe mode. figure 50 window watchdog definitions 15.2.3 watchdog setting check sum a check sum bit is part of the spi commend to trig ger the watchdog and to set the watchdog setting. the sum of the 8 data bits in the register wwd_ctrl needs to have even parity (see equation (3) ). this is realized by either setting the bit checksum to 0 or 1. if the check sum is wrong, then the spi command is ignored, i.e. the watchdog is not triggered or the settings are not changed and the bit spi_fail is set. the checksum is calculated by taking all 8 data bits into account. the written value of the reserved bit 3 of the wwd_ctrl register is considered (even if read as ?0? in the sp i output) for checksum calc ulation, i.e. if a 1 is written on the reserved bit position, then a 1 will be used in the checksum calculation.

data sheet 115 rev. 1.1, 2014-09-26 TLE9263QX serial peripheral interface 16.2 failure signalization in the spi data output when the microcontroller sends a wrong spi command to the sbc, the sbc ignores the information. wrong spi commands are either invalid sbc mode commands or commands which are prohibited by the state machine to avoid undesired device or system states (see below). in this case the diagnosis bit ? spi_fail ? is set and the spi write command is ignored (mostly no partia l interpretation). this bit can be only reset by actively clearing it via a spi command. invalid spi commands leading to spi_fail are listed below: ? illegal state transitions: going from sbc stop to sbc sl eep mode. in this case the sbc enters in addition the sbc restart mode; trying to go to sbc stop or sbc sl eep mode from sbc init mode. in this case sbc normal mode is entered; ? uneven parity in the data bit of the wd_ctrl register. in this case the watchdog trigger is ignored or the new watchdog settings are ignored respectively; ? in sbc stop mode: attempting to change any spi sett ings, e.g. changing the watchdog configuration, pwm settings and hs configuration settings during sbc stop mode, etc.; the spi command is ig nored in this case; only wd trigger, returning to normal mode, triggeri ng a sbc soft reset, and read & clear status registers commands are valid spi comma nds in sbc stop mode; ? when entering sbc stop mode and wk_stat_1 and wk_stat_2 are not cleared; spi_fail will not be set but the int pin will be triggered; ? changing from sbc stop to normal mode and changing the other bits of the m_s_ctrl register. the other modifications will be ignored; ? sbc sleep mode: attempt to go to sleep mode when all bits in the bus_ctrl_1 , bus_ctrl_2 and wk_ctrl_2 registers are cleared. in this case the spi_fail bit is set and the sbc enters restart mode. even though the sleep mode command is not entered in this case, the rest of the command (e.g modifying vcc2 or vcc3) is executed and the values stay unchanged during sbc restart mode; note: at least one wake source must be activated in order to avoid a deadlock situation in sbc sleep mode, i.e. the sbc would not be able to wake up anymore. if the only wake source is a timer and the timer is off then the sbc will wake immedi ately from sleep mode and enter restart mode; no failure handling is done for the attempt to go to sbc stop mode when all bits in the registers bus_ctrl_1 , bus_ctrl_2 and wk_ctrl_2 are cleared because the microcontroller can leave this mode via spi; ? if vcc3 load sharing vcc3_ls is enabled and the microcontroller tries to clear the bit, then the rest of the command executed but vcc3_ls will remain set; ? attempt to enter sbc sleep mode if wk_meas is set to ?1? and only wk1_en or wk2_en are set as wake sources. also in this case the spi_fail bit is set and the sbc enters restart mode; ? setting a longer or equal on-time than th e timer period of the respective timer; ? sdi stuck at high or low, e.g. sdi received all ?0? or all ?1?; note: there is no spi fail information for unused addresses. signalization of the err flag (high ac tive) in the spi data output (see figure 55 ): the err flag presents an additional di agnosis possibility for th e spi communication. the err flag is being set for following conditions: ? in case the number of received spi clocks is not 0 or 16, ? in case ro is low and spi frames are being sent at the same time.
data sheet 116 rev. 1.1, 2014-09-26 TLE9263QX serial peripheral interface note: in order to read the spi err flag properly, clk must be low when csn is triggere d, i.e. the err bit is not valid if the clk is high on a falling edge of csn the number of received spi clocks is not 0 or 16: the number of received input clocks is supervised to be 0- or 16 clock cycles and the input word is discarded in case of a mismatch (0 clock cycle to enable err signa lization). the error logic also recognizes if clk was high during csn edges. both errors - 0 bit and 16 bit clk mismatch or clk high during csn edges - are flagged in the following spi output by a ?high? at the data output (sdo pin, bit err) befo re the first rising edge of the clock is received. the complete spi command is ignored in this case. ro is low and spi frames are being sent at the same time: the err flag will be set when the ro pin is triggered (dur ing sbc restart) and spi fram es are being sent to the sbc at the same time. the behavior of the err flag will be signalized at the next spi command for below conditions: ? if the command begins when ro is high and it ends when ro is low, ? if a spi command will be sent while ro is low, ? if a spi command begins when ro is low and it ends when ro is high. and the sdo output will behave as follows: ? always when ro is low then sdo will be high, ? when a spi command begins with ro is low and ends when ro is high, then the sdo should be ignored because wrong data will be sent. note: it is possible to quickly check fo r the err flag without sending any data bits. i.e. only the csn is pulled low and sdo is observed - no spi clocks are sent in this case note: the err flag could also be set after the sbc has entered sbc fail-safe mode because the spi communication is st opped immediately.
data sheet 117 rev. 1.1, 2014-09-26 TLE9263QX serial peripheral interface 16.3 spi programming for the TLE9263QX, 7 bits are used or the address sele ction (bit6...0). bit 7 is used to decide between read only and read & clear for the status bits, and between wr ite and read only for configuration bits. for the actual configuration and status information, 8 data bits (bit15...8) are used. writing, clearing and reading is done byte wise. the sp i status bits are not cleared automatically and must be cleared by the microcontrolle r, e.g. if the tsd2 was se t due to over temp erature. the configuration bits will be partially automatically cleared by th e sbc - please refer to the individual registers description for detailed information. during sbc restart mode the spi communicati on is ignored by the sbc, i. e. it is no t interpreted. there are two types of spi registers: ? control registers: those are the registers to config ure the sbc, e.g. sbc mode, watchdog trigger, etc ? status registers: those are the registers where the status of the sbc is signalled, e.g. wake events, warnings, failures, etc. for the status registers, the requested informat ion is given in the sa me spi command in do. for the control registers, also the st atus of the respective by te is shown in the same spi command. however, if the setting is changed this is only shown with the next spi command (it is only valid after csn high) of the same register. the sbc status information from the spi status regist ers, is transmitted in a compressed way with each spi response on sdo in the so called status information field register (see also figure 56 ). the purpose of this register is to quickly signal the information to the mi crocontroller if there was a ch ange in one of the spi status registers. in this way, the microcontroller does not need to read constantly all the spi status registers but only those registers, wh ich were changed. each bit in the status information fiel d represents a spi stat us register (see table 28 ). as soon as one bit is set in one of the status register s, then the respective bit in the status information field re gister will be set. the register wk_lvl_stat is not included in the status in formation field. this is listed in table 28 . for example if bit 0 in the status information field is set to 1, one or more bits of the register 100 0001 ( sup_stat_1 ) is set to 1. then this register needs to be read in a second spi command. the bit in the status information field will be set to 0 when all bits in the regist er 100 0001 are set back to 0. table 28 status information field bit in status information field corresponding address bit status register description 0 100 0001 sup_stat_1: supply stat us -vshs fail, vccx fail, por 1 100 0010 therm_stat: thermal protection status 2 100 0011 dev_stat: device status - mode before wake, wd fail, spi fail, failure 3 100 0100 bus_stat: bus fa ilure status: can, linx; bus_stat_1 & bus_stat_2 are a combinational or 4 100 0110 wk_stat_1, wk_stat_2: wake source status; status bit is set as combinat ional or of both registers 5 100 0000 sup_stat_2: vcc1_warn/ov, vcc3 status 6 101 0100 hs_oc_ot_stat: high-side over load status 7 101 0101 hs_ol_stat: high-side open load status

data sheet 119 rev. 1.1, 2014-09-26 TLE9263QX serial peripheral interface 16.4 spi bit mapping the following figures show the mapping of the regist ers and the spi bits of the respective registers. the control registers ?000 0000? to ?001 1110? are read/wri te register. depending on bi t 7 the bits are only read (setting bit 7 to ?0?) or also written (setting bit 7 to ?1 ?). the new setting of the bit after write can be seen with a new read / write command. the registers ?100 0000? to ?111 1110? are status regi sters and can be read or read with clearing the bit (if possible) depending on bit 7. to clear a data byte of on e of the status r egisters bit 7 must be set to 1. the registers wk_lvl_stat , and fam_prod_stat are an exception as they show the actual voltage level at the respective wk pin (low/high), or a fixed family/ product id respectively and can t hus not be cleared. it is recommended for proper diagnosis to clear respective status bits for wake events or failure. however, in general it is possible to enable drivers withou t clearing the respec tive failure flags. when changing to a different sbc mode, certain configurations bits will be cleared automatica lly or modified: ? the sbc mode bits are updated to the actual status, e.g. when returning to normal mode ? when changing to a low-power mode (stop/sleep), the di agnosis bits of the switches and transceivers are not cleared. fox will stay activated if it was triggered before. ? when changing to sbc stop mode, the can a nd lin control bits will not be modified. ? when changing to sbc sleep mode, th e can and lin control bits will be m odified if they were not off or wake capable before. ? hsx, vcc2 and vcc3 will stay on wh en going to sleep-/stop mode (configu ration can only be done in normal mode). diagnosis is active (oc, ol, ot). in case of a failure the switch is turned off and no wake-up is issued ? the configuration bits for hsx and vcc2 in stand-al one configuration are cleared in sbc restart mode. fox will stay activated if it was triggered before. depending on the respective configuration, can/ lin transceivers will be either off, woken or still wake capable. note: the detailed behavior of the respective spi bits and control functions is described in chapter 16.5 , chapter 16.6 .and in the respective module chapter. the bit type be mark ed as ?rwh? in case the sbc will modify respective control bits.
