2008-09-30 caution in setting the ua rt noise rejection time when uart is used, settings of rxdnc are limited depend ing on the transfer clock specified by brg. the com- bination "o" is available but please do not select the combination "?". the transfer clock generated by timer/counter in terrupt is calculated by the following equation : transfer clock [hz] = time r/counter source clock [hz] ttreg set value brg setting transfer clock [hz] rxdnc setting 00 (no noise rejection) 01 (reject pulses shorter than 31/fc[s] as noise) 10 (reject pulses shorter than 63/fc[s] as noise) 11 (reject pulses shorter than 127/fc[s] as noise) 000 fc/13 o o o ? 110 (when the transfer clock gen- erated by timer/counter inter- rupt is the same as the right side column) fc/8 o ? ? ? fc/16 o o ? ? fc/32ooo ? the setting except the a b o v eoooo

datasheet modifications: i 2 c bus mode control the following problem is included in the explanation of the i 2 c bus function of this data sheet. it will guide the correction as follo ws. please read it for the explanat ion of this data sheet as follows. section: ?i 2 c bus mode control? ? in the explanation of the serial bus interface control register 1 1. delete the setting examples where the serial clock frequency exceeds 100 khz. 2. add the following note. note: this i 2 c bus circuit does not support the fast mode. it supports the standard mode only. although the i 2 c bus circuit itself allows the setting of a baud rate over 100 kbps, the compliance with the i 2 c specification is not guaranteed in that case. ? in ?(3) serial clock? 1. add the following sentence about the communication baud rate. a. clock source the sck (bits 2 to 0 in the sbicr1) is used to select a maximum transfer frequency outputed on the scl pin in the master mode. set a communication baud rate that meets the i 2 c bus specification, such as the shortest pulse width of t low, based on the equations shown below. in both master mode and slave mode, a pulse wi dth of at least 4 machine cycles is require for both ?h? and ?l? levels. t low = 2 n /f c t high = 2 n /f c + 8/f c fscl = 1/(t low + t high ) 000 : reserved 001 : reserved 010 : 58.8 011 : 30.3 100 : 15.4 101 : 7.75 110 : 3.89 (note) (note) khz khz khz khz khz at fc = 8mhz (output on scl pin) sck serial clock selection 111 : reserved write- only toshiba microcontrollers 870 family (tmp87ch48u) (tmp87ch48df) (tmp87cm48u) (tmp87cm48df) tmp87ch48i (tmp87ph48u) (tmp87ph48df) (tmp87pm48u) (tmp87pm48df) 2008-02-08 tmp87ch48/cm48
tmp87ch48/cm48 i 2008-03-06 document change notification ? ? the purpose of this notification is to inform customers about the launch of the pb-free version of the device. the introduction of a pb-f ree replacement affects the datash eet. please understand that this notification is intended as a temporary su bstitute for a revision of the datasheet. changes to the datasheet may include the following, though not all of them may apply to this particular device. ? 1. part number example: tmpxxxxxxf tmpxxxxxxfg all references to the previous part number were left unchanged in body text. the new part number is indicated on the prelims pages (cover page and this notification). ? 2. package code and package dimensions example: lqfp100-p-1414-0.50c lqfp100-p-1414-0.50f all references to the previous package code and package dimensions were left unchanged in body text. the new ones are indicated on the prelims pages. ? 3. addition of notes on lead solderability now that the device is pb-free, notes on lead solderability have been added. ? 4. restrictions on product use the previous (obsolete) provision might be left unchanged on page 1 of body text. a new replacement is included on the next page. ? 5. publication date of the datasheet the publication date at the lower right corner of the prelims pages applies to the new device.
