(1) Prescaler mode register (PRSM)
Cautions 1. Do not change the values of BGCS1 and BGCS0 during transmission/reception.
The PRSM register controls generation of the clock of the watch timer and A/D converter.
This register can be read or written in 8-bit or 1-bit units.
Control register
2. Set the PRSM register before setting the CE bit to 1.
3. Set the PRSM and PRSCM registers in accordance with the main clock frequency to be
