(2) Prescaler compare registers 1 to 3 (PRSCM1 to PRSCM3)
The transmission/reception clock is generated by dividing the main clock. The baud rate generated from the main clock
Caution Set f
Remark
The PRSCM1 to PRSCM3 registers are 8-bit compare registers.
These registers can be read or written in 8-bit units.
Reset sets these registers to 00H.
