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 control.
RCR2 is initialized to H'09 by a power-on reset or in deep standby mode. Bits other than the
RTCEN and START bits are initialized by a manual reset. It is not initialized in software 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 designated
[Clearing condition]
•
1: Interrupts generated with the period designated by
[Setting condition]
•
Interrupt Enable Flags
These bits specify the periodic interrupt.
000: No periodic interrupts generated
001: Periodic interrupt generated every 1/256 second
010: Periodic interrupt generated every 1/64 second
011: Periodic interrupt generated every 1/16 second
100: Periodic interrupt generated every 1/4 second
101: Periodic interrupt generated every 1/2 second
110: Periodic interrupt generated every 1 second
111: Periodic interrupt generated every 2 seconds
