frequency = φT2 (fc/16), the frequency divider N (BR1CR<BR1S3:0>) = 5, and
BR1CR<BR1ADDE> = 0, the baud rate in UART mode is as follows:
frequency = φT0, the frequency divider N (BR1CR<BR1S3:0>) = 7, K
(BR1ADD<BR1K3:0>) = 3, and BR1CR <BR1ADDE> = 1, the baud rate in UART
Mode is as follows:
Baud rate =
Channels 0, 1). The method for calculating the baud rate is explained below:

Note: The N + (16 − K)/16 division function is disabled and setting
Baud rate =
For example, when the source clock frequency (fc) = 12.288 MHz, the input clock
Accordingly, when the source clock frequency (fc) = 4.8 MHz, the input clock
Table 3.9.3 show examples of UART mode transfer rates.
Additionally, the external clock input is available in the serial clock. (Serial
In UART mode
In I/O interface mode
Baud rate = External clock input frequency ÷ 16
It is necessary to satisfy (External clock input cycle) ≥ 4/fc
Baud rate = External clock input frequency
It is necessary to satisfy (External clock input cycle) ≥ 16/fc
BR1ADD<BR1K3:0> is invalid.
