17.3.17 RTC Control Register 2 (RCR2)
RCR2 is a register for periodic interrupt control, 30-second adjustment ADJ, divider circuit
RESET, and RTC count control.
RCR2 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
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
Interrupt Enable 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
Periodic Interrupt Flag
designated by the bits PES2 to PES0.
[Clearing condition] When 0 is written to PEF
designated by the PES2 to PES0 bits.
[Setting condition] When an interrupt is
generated with the period designated by the
bits PES0 to PES2 or when 1 is written to the
PEF flag
