Interrupt Enable Flags
These bits specify the periodic interrupt.
000: No periodic interrupts generated
001: Setting prohibited
010: Periodic interrupt generated every 1/64 second
011: Periodic interrupt generated every 1/16 second
100: Periodic interrupt generated every 1/4 second

R/W
RTC_X1 Clock Control
Controls the function of RTC_X1 pin.
0: Halts the on-chip crystal oscillator/disables the
external clock input.
1: Runs the on-chip crystal oscillator/enables the
external clock input.

R/W
30-Second
Adjustment
When 1 is written to the ADJ bit, times of 29 seconds or
less will be rounded to 00 seconds and 30 seconds or
more to 1 minute. The divider circuit (prescaler and
R64CNT) will be simultaneously reset. This bit always
reads 0.
less will be rounded to 00 seconds and 30 seconds or
more to 1 minute. The divider circuit (prescaler and
R64CNT) will be simultaneously reset. This bit always
reads 0.
0: Runs normally.
1: 30-second adjustment.
