(1) Peripheral enable register 0 (PER0)
(2) Real-time counter control register 0 (RTCC0)
Symbol
PER0
PER0 is used to enable or disable use of each peripheral hardware macro. Clock supply to a hardware macro
that is not used is stopped in order to reduce the power consumption and noise.
When the real-time counter is used, be sure to set bit 7 (RTCEN) of this register to 1.
PER0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
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.
