Section 15 Realtime Clock (RTC)
15.3.17 RTC Control Register 2 (RCR2)
RCR2 is a register for periodic interrupt control, 30-second adjustment ADJ, divider circuit
RESET, and RTC count start/stop control.
RCR2 is an 8-bit readable/writable register. It is initialized to H'09 by a power-on reset. It is
initialized except for RTCEN and START by a manual reset. It is not initialized in standby mode,
and retains its contents.

Description
Periodic Interrupt Flag
Indicates interrupt generation with the period
designated by the PES2 to PES0 bits. When set
to 1, PEF generates periodic interrupts.
0: Interrupts not generated with the period
1: Interrupts generated with the period
Periodic Interrupt Flags
These bits specify the periodic interrupt.
000: No periodic interrupts generated
001: Periodic interrupt generated every 1/256
010: Periodic interrupt generated every 1/64
011: Periodic interrupt generated every 1/16
100: Periodic interrupt generated every 1/4
101: Periodic interrupt generated every 1/2
110: Periodic interrupt generated every 1 second
111: Periodic interrupt generated every 2
designated by the PES bits.
Clearing condition: When 0 is written to PEF
designated by the PES bits.
Setting condition: When an interrupt is
generated with the period designated by the
PES0 to PES2 bits or when 1 is written to the
PEF flag
