Integer divider (N divider)
N + (16 − K)/16 divider (UART mode only)
frequency divider N (BR0CR<BR0S3:0>) = 8, and BR0CR<BR0ADDE> = 0, the
baud rate in UART mode is as follows:
frequency divider N (BR0CR<BR0S3:0>) = 6, K (BR0ADD<BR0K3:0>) = 8, and
BR0CR<BR0ADDE> = 1, the baud rate is as follows:

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