Description
Periodic Interrupt Interval
These bits specify the periodic interrupt interval.
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 seconds
Controls the operation of the crystal oscillator for
the RTC.
0: Halts the crystal oscillator for the RTC.
1: Runs the crystal oscillator for the RTC.
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 will be simultaneously reset. This bit is
always read as 0.
0: Runs normally.
1: 30-second adjustment.
Reset
When 1 is written, initializes the divider circuit
(RTC prescaler and R64CNT). This bit is always
read as 0.
0: Runs normally.
1: Divider circuit is reset.
