Integer divisor (N divisor)
N + (16 − K)/16 divisor (only in UART mode)
(fc/16), and frequency divisor is N(BR0CR<BR0S3:0>) = 5 BR0CR<BRADD0> = 0,
the baud rate in UART mode becomes as follows:
Note: + (16 − K)/16 division function is disabled, and setting BRADD0<BR0K3:0> is
frequency divisor is N (BR0CR<BR0S3:0>) = 7, “K” (BRADD0<BR0K3:0>) = 3,
BR0CR<BRADD0> = 1, the baud rate in UART mode becomes as follows.
channel 0 to 3.) How to calculate a baud rate is explained below.

For example, when the source clock (fc) is 12.288 MHz, the input clock is φT2
Accordingly, when source clock (fc) is 4.8 MHz, the input clock is φT0, and
Table 3.9.2, Table 3.9.3 show an example of the transfer rate in UART mode.
Additionally, the external clock input is available in the serial clock. (Serial

Baud rate = External clock input ÷ 16
It is necessary to satisfy (External clock input cycle) ≥ 4/fc + 20 [ns]
Baud rate = External clock input
It is necessary to satisfy (External clock input cycle) ≥ 16/fc [ns].
