(1) Peripheral enable register 0 (PER0)
(2) Real-time counter control register 0 (RTCC0)
The RTCC0 register is an 8-bit register that is used to start or stop the real-time counter operation, control the
RTCCL and RTC1HZ pins, and set a 12- or 24-hour system and the constant-period interrupt function.
RTCC0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
This register controls the clock supplied to peripheral functions other than the real-time counter. By stopping the
clock supplied to such peripheral functions, the power consumption can be reduced.
PER0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Address: FF25H
Symbol
PER0
Note To output the subsystem clock by using the PCL function while in the subsystem clock HALT mode,
Caution Be sure to clear bits 0 to 6 of PER0 to “0”.
