HANDLING DEVICES
1. Be careful never to exceed maximum rated voltages (preventing latch-up)
In CMOS IC devices, a condition known as latch-up may occur if voltages higher than VCC or lower than VSS are applied to input or output pins other than medium-or high-voltage pins, or if the voltage applied between VCC and VSS pins exceeds the rated voltage level. When latch-up occurs, the power supply current increases rapidly causing the possibility of thermal damage to circuit elements. Therefore it is necessary to ensure that maximum ratings are not exceeded in circuit operation. Similarly, when turning the analog power supply on or off, it is necessary to ensure that the analog power supply voltages (AVCC and AVRH) and analog input voltages do not exceed the digital power supply (VCC) .
2. Treatment of unused pins
Leaving unused input pins unconnected can cause abnormal operation or latch-up, leading to permanent damage. Unused input pins should always be pulled up or down through resistance of at least 2 k . Any unused input/output pins may be set to output mode and left open, or set to input mode and treated the same as unused input pins.
3. Treatment of Power Supply Pins (VCC/VSS)
When multiple VCC/VSS pins are present, device design considerations for prevention of latch-up and unwanted electromagnetic interference, abnormal strobe signal operation due to ground level rise, and conformity with total output current ratings require that all power supply pins must be externally connected to power supply or ground. Consideration should be given to connecting power supply sources to the VCC/VSS pins of this device with as low impedance as possible. It is also recommended that a bypass capacitor of approximately 0.1 F be placed between the VCC and VSS lines as close to this device as possible.
4. Crystal Oscillator Circuits
Noise around the X0/X1, or X0A/X1A pins may cause this device to operate abnormally. In the interest of stable operation it is strongly recommended that printed circuit board artwork places ground bypass capacitors as close as possible to the X0/X1, X0A/X1A and crystal oscillator (or ceramic oscillator) and that oscillator lines do not cross the lines of other circuits.
5. Precautions when turning the power supply on
In order to prevent abnormal operation in the chip's internal step-down circuits, a voltage rise time during poweron of 50 s (0.2 V to 2.7 V) or greater should be assured.
6. Supply Voltage Stabilization
Even within the operating range of VCC supply voltage, rapid voltage fluctuations may cause abnormal operation. As a standard for power supply voltage stability, it is recommended that the peak-to-peak VCC ripple voltage at commercial supply frequency (50/60 Hz) be 10 % or less of VCC, and that the transient voltage fluctuation be no more than 0.1 V/ms or less when the power supply is turned on or off.
7. Proper power-on/off sequence
The A/D converter power (AVCC, AVRH) and analog input (AN0 to AN7) must be turned on after the digital power supply (VCC) is turned on. The A/D converter power (AVCC, AVRH) and analog input (AN0 to AN7) must be shut off before the digital power supply (VCC) is shut off. Care should be taken that AVRH does not exceed AVCC. Even when pins used as analog input pins are doubled as input ports, be sure that the input voltage does not exceed AVCC. 16 DS07-13722-11E

MB90485B series only I2C pin P77 and P76 are N-ch open drain pin (without P-ch) . However, MB90V485B uses the N-ch open drain pin (with P-ch) . P20 to P27, P30 to P37, P40 to P47 and P70 to P77 are also used as 3 V/5 V I/F pin. As for MB90V485B, input pins (PWC0, PWC1, PWC2/EXTC/SCL and SDA pins) for PWC/ PG/I2C become CMOS input. Note : In the above diagram, I/O ports share internal function blocks and pins. However, when a set of pins is used with an internal module, it cannot also be used as an I/O port. 18 DS07-13722-11E

*1 : The value is set to " " on MB90485B series only. *2 : The initial value of this bit is "XX000000B" on MB90485B series only. When a set of pins is functioning as a port, the corresponding signal pins are controlled as follows. 0 : Input mode. 1 : Output mode. Reset to "0". Notes : When any of these registers are accessed using a read-modify-write type instruction (such as a bit set instruction) , the bit specified in the instruction will be set to the indicated value. However, the contents of output registers corresponding to any other bits having input settings will be rewritten to the input values of those pins at that time. For this reason, when changing any pin that has been used for input to output, first write the desired value to the PDR register before setting the DDR register for output. P76, P77 (MB90485B series only) This port has no DDR. To use P77 and P76 as I2C pins, set the PDR value to "1" so that port data remains enabled (to use P77 and P76 for general purposes, disable I2C) . The port is an open drain output (with no P-ch) . To use it as an input port, therefore, set the PDR to "1" to turn off the output transistor and add a pull-up resistor to the external output. 34 DS07-13722-11E

5. 8/16-bit PPG
The 8/16-bit PPG is an 8-bit reload timer module that produces a PPG output using a pulse from the timer operation. Hardware resources include 6 x 8-bit down counters, 12 x 8-bit reload timers, 3 x 16-bit control registers, 6 x external pulse output pins, and 6 x interrupt outputs. Note that MB90480B/485B series has six channels for 8-bit PPG use, which can also be combined as PPG0 + PPG1, PPG2 + PPG3, and PPG4 + PPG5 to operate as a three-channel 16-bit PPG. The following is a summary of functions. * 8-bit PPG output 6-channel independent mode : Provides PPG output operation on six independent channels. * 16-bit PPG output operation mode : Provides 16-bit PPG output on three channels. The six original channels are used in combination as PPG0 + PPG1, PPG2 + PPG3, and PPG4 + PPG5. * 8 + 8-bit PPG output operation mode : Output from PPG0 (PPG2/PPG4) is used as clock input to PPG1 (PPG3/ PPG5) to provide to 8-bit PPG output at any desired period length. * PPG output operation : Produces pulse waves at any desired period and duty ratio. The PPG module can also be used with external circuits as a D/A converter. (1) Register List PPGC0/PPGC2/PPGC4 (PPG0/PPG2/PPG4 operation mode control register) 00003AH 00003CH 00003EH

10. 16-bit Reload Timer
The 16-bit reload timer provides a choice of functions, including internal clock signals that count down in synchronization with three types of internal clock, as well as an event count mode that counts down at specified edge detection events in pulse signals input from external pins. This timer defines an underflow as a change in count value from 0000H to FFFFH. Thus an underflow will occur when counting from the value "reload register setting value + 1". The choice of counting operations includes reload mode, in which the count setting values is reloaded and counting continues following an underflow event, and one-shot mode, in which an underflow event causes counting to stop. An interrupt can be generated at counter underflow, and the timer is DTC compatible. (1) Register List * TMCSR (Timer control status register) Timer control status register (high) (TMCSR)

19. Chip Select Function Description
The chip select module generates a chip select signals, which are used to facilitate connections to external memory devices. The MB90480B/485B series has four chip select output pins, each having a chip select area register setting that specifies the corresponding hardware area and select signal that is output when access to the corresponding external address is detected. * Chip select function features The chip select function uses two 8-bit registers for each output pin. One of these registers (CARx) is able to detect memory areas in 64 Kbytes units by specifying the upper 8-bit of the address for match detection. The other register (CMRx) can be used to expand the detection area beyond 64 Kbytes by masking bits for match detection. Note that during external bus holds, the CS output is set to high impedance.

23. Address Match Detection Function
When the address is equal to a value set in the address detection register, the instruction code loaded into the CPU is replaced forcibly with the INT9 instruction code (01H). As a result, when the CPU executes a set instruction, the INT9 instruction is executed. Processing by the INT#9 interrupt routine allows the program patching function to be implemented. Two address detection registers are supported. An interrupt enable bit is prepared for each register. If the value set in the address detection register matches an address and if the interrupt enable bit is set at "1", the instruction code loaded into the CPU is replaced forcibly with the INT9 instruction code.

However, if the maximum current to/from and input is limited by some means with external components, the ICLAMP rating supersedes the VI rating. *4 : Maximum output current is defined as the peak value for one of the corresponding pins. *5 : Average output current is defined as the average current flow in a 100 ms interval at one of the corresponding pins. *6 : Average total output current is defined as the average current flow in a 100 ms interval at all corresponding pins. *7 : Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67, P70 to P77, P80 to P87, P90 to P97, PA0 to PA3 Use within recommended operating conditions. Use at DC voltage (current) . The + B signal should always be applied with a limiting resistance placed between the + B signal and the microcontroller. The value of the limiting resistance should be set so that when the + B signal is applied the input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.

(Continued) Note that when the microcontroller drive current is low, such as in the power saving modes, the + B input potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect other devices. Note that if a + B signal is input when the microcontroller power supply is off (not fixed at 0 V) , the power supply is provided from the pins, so that incomplete operation may result. Note that if the + B input is applied during power-on, the power supply is provided from the pins and the resulting supply voltage may not be sufficient to operate the power-on reset. Care must be taken not to leave the + B input pin open. Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input pins, etc.) cannot accept + B signal input.

P76 and P77 is N-ch open drain pin. *9 : As for P76 and P77 (N-ch open drain pin) , even if using at 3 V simplicity (VCC3 = VCC5) , the ratings are applied. WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
