(1) Peripheral enable register 2 (PER2)
Address: F00F2H
Symbol
PER2
PER2 is used to enable or disable supplying the clock to the peripheral hardware. Clock supply to a hardware
macro that is not used is stopped in order to reduce the power consumption and noise.
When using timer array unit TAUS and the inverter control function, be sure to set bit 0 (TAU0EN) and bit 1
(TAUOPEN) of this register to 1.
PER2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears PER2 to 00H.
Cautions 1. When setting timer array unit TAUS and the inverter control function, be sure to set
TAUOPEN
TAU0EN
2. Be sure to clear bits 2 to 7 of the PER2 register to 0.

TAU0EN and TAUOPEN to 1 first. If TAU0EN and TAUOPEN = 0, writing to a control
register of timer array unit TAUS and the inverter control function is ignored, and all read
values are default values (except for timer input select register 0 (TIS0), input switch
control register (ISC), noise filter enable registers 1, 2 (NFEN1, NFEN2), port mode
registers 0, 1, 3, 5, 7(PM0, PM1, PM3, PM5, PM7), port registers 0, 1, 3, 5, 7 (P0, P1, P3, P5,
P7)).
After reset: 00H
