16.8.1 Baud rate generation
clock is obtained by the following equation.

(2) Prescaler compare registers 1, 2 (PRSCM1, PRSCM2)
The transmission/reception clock is generated by dividing the main clock. The baud rate generated from the main
Caution Set f
Remark
The PRSCM1 and PRSCM2 registers are 8-bit compare registers.
These registers can be read or written in 8-bit units.
Reset sets these registers to 00H.
