(1) Peripheral enable register 1 (PER1)
This register is used to enable or disable supplying the clock to the peripheral hardware. Power consumption and
noise are reduced by stopping the clock supply to unused hardware.
Make sure to set bit 3 (OACMPEN) to 1 to use a comparator or a programmable gain amplifier.
The PER1 register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Cautions 1. Make sure to set the OACMPEN bit to 1 first, when setting the comparator or programmable
