If you have any questions, please contact your local Toshiba sales representative. September 2008 Caution in Setting the UART Noise Rejection Time With regard to the TLCS-870 TLCS-870, TLCS-870/X TLCS-870/X and TLCS-870/C TLCS-870/C Series of Toshiba's 8-bit microcontrollers listed above, please be informed that certain combinations of transfer clock frequency and noise rejection time should not be used in the UART (asynchronous serial interface) as explained below. If you need further information, please contact your local Toshiba sales representative. [Applicable Usage Conditions] This caution applies when the timer/counter interrupt is selected as a transfer clock of the UART and the transfer clock frequency (fc) and the RXD input noise rejection time are set to one of the combinations shown in the table below. Under any other conditions, the noise rejection can be used without any problem. Timer/counter interrupt (BRG=110) RXD input noise rejection time setting Reject pulses shorter than 31/fc as noise (RXDNC=01) fc/16 Reject pulses shorter than 63/fc as noise (RXDNC=10) fc/32 Receive operation (RXE=1) Transfer clock select Transfer clock frequency [Hz] (Note) fc/8 Communication mode setting Reject pulses shorter than 127/fc as noise (RXDNC=11) fc frequency [MHz] 1.229 2.458 4.915 9.830 1.229 2.458 4.915 9.830 19.661 1.229 2.458 4.915 9.830 19.661 Communication speed [bps] 9600 19200 38400 76800 4800 9600 19200 38400 76800 2400 4800 9600 19200 38400 Note: The transfer clock is calculated by the following equation: Transfer clock [Hz] = Timer/counter source clock [Hz] ÷ TTREG set value [Problem] In receive operation (RXE=1), input data on the RXD pin may not be received properly. [Workaround] If you are using the UART with one of the above noise rejection time settings, disable the noise rejection or change the noise rejection time to a shorter period. 1/1 2008-9
