12.2.16 RTC Control Register 2 (RCR2)
The RTC control register 2 (RCR2) is an 8-bit read/write register for periodic interrupt control, 30-
second adjustment ADJ, divider circuit RESET, and RTC count start/stop control. It is initialized
to H'09 by a power-on reset. It is not initialized by a manual reset or in standby mode, and retains
its contents.
Bit 7—Periodic Interrupt Flag (PEF): Indicates interrupt generation with the period designated by
the PES bits. When set to 1, PEF generates periodic interrupts.
