Integer divider (N divider)
φT2, the frequency divider N (BR0CR<BR0S3:0>) = 8, and BR0CR<BR0ADDE> = 0,
the baud rate in UART Mode is as follows:
N+(16-K)/16 divider (UART Mode only)
φT2, the frequency divider N (BR0CR<BR0S3:0>) = 6, K (BR0ADD<BR0K3:0>) = 8,
and BR0CR <BR0ADDE> = 1, the baud rate in UART Mode is as follows:
0). The method for calculating the baud rate is explained below:
For example, when the source clock frequency (f
Accordingly, when the source clock frequency (fc) = 15.9744 MHz, the input clock is
Table 3.14.2 show examples of UART Mode transfer rates.
Additionally, the external clock input is available in the serial clock. (Serial Channel

Baud Rate
Baud Rate
Baud rate = external clock input frequency ÷ 16
It is necessary to satisfy (external clock input cycle) ≥ 4/f
Baud rate = external clock input frequency
It is necessary to satisfy (external clock input cycle) ≥ 16/f
