The alarm features and characteristics are:
• Configurable from half a second to one year
• Enabled using the ALRMEN bit (ALRMCFG<7>,
• Offers one-time and repeat alarm options
16.3.1
The alarm feature is enabled using the ALRMEN bit.
This bit is cleared when an alarm is issued. The bit will
not be cleared if the CHIME bit = 1 or if ALRMRPT ≠ 0.
The interval selection of the alarm is configured
through the ALRMCFG bits (AMASK<3:0>). (See
Figure 16-5.) These bits determine which and how
many digits of the alarm must match the clock value for
the alarm to occur.

The alarm can also be configured to repeat based on a
preconfigured interval. The number of times this occurs
after the alarm is enabled is stored in the ALRMRPT
register.

While the alarm is enabled (ALRMEN = 1),
changing any of the registers – other than
the RTCCAL, ALRMCFG and ALRMRPT
registers and the CHIME bit – can result in
a false alarm event leading to a false
alarm interrupt. To avoid this, only change
the timer and alarm values while the alarm
is disabled (ALRMEN = 0). It is recom-
mended
ALRMRPT registers and CHIME bit be
changed when RTCSYNC = 0.
