Alarm
The output of the alarm comparator is enabled when this bit
is set high. When a comparison occurs between the
seconds, minutes and hours time and alarm counters, the
interrupt output is activated. When loading the time counters,
this bit should be set low to avoid a false interrupt. This is not
required when loading the alarm counters. See "Functional
Description", INT for explanation of alarm delay on page 10.
Periodic Select
The value in these 4 bits will select the frequency of the
periodic output. (See Table 3).
