Alarm registers
When one or more of the alarm registers are loaded with a valid minute, hour, day or
weekday and its corresponding AE (Alarm Enable) bit is a logic 0, then that
information will be compared with the current minute, hour, day and weekday. When
all enabled comparisons rst match, the bit AF (Alarm Flag) is set.
AF will remain set until cleared by software. Once AF has been cleared it will only be
set again when the time increments to match the alarm condition once more. Alarm
registers which have their AE bit set at logic 1 will be ignored.
