FIGURE 18-6:
18.4
The timer and alarm continue to operate while in Sleep
mode. The operation of the alarm is not affected by
Sleep, as an alarm event can always wake up the CPU.
The Idle mode does not affect the operation of the timer
or alarm.
18.5
18.5.1
When a device Reset occurs, the ALRMRPT register is
forced to its Reset state, causing the alarm to be
disabled (if enabled prior to the Reset). If the RTCC
was enabled, it will continue to operate when a basic
device Reset occurs.

18.5.2
The RTCCFG and ALRMRPT registers are reset only
on a POR. Once the device exits the POR state, the
clock registers should be reloaded with the desired
values.
The timer prescaler values can be reset only by writing
to the SECONDS register. No device Reset can affect
the prescalers.
