Caution in Setting the UART Noise Rejection Time
When UART is used, settings of RXDNC are limited depending on the transfer clock specified by BRG. The combination "O" is available but please do not select the combination "–".
The transfer clock generated by timer/counter interrupt is calculated by the following equation : Transfer clock [Hz] = Timer/counter source clock [Hz] ÷ TTREG set value
BRG setting
Transfer clock [Hz]
000
fc/13
110 (When the transfer clock generated by timer/counter interrupt is the same as the right
side column)
fc/8 fc/16
fc/32
The setting except the above
00 (No noise rejection)
O O O
RXDNC setting
01 (Reject pulses shorter than 31/fc[s] as noise)
10 (Reject pulses shorter than 63/fc[s] as noise)
