ALARM Reset Cautions
“0” is output to ALARM when the timer and alarm register
contents match for the minute, hour, day and date
items while alarms are enabled.
After an alarm reset, however, items for which nothing
has been written are considered to match, regardless
of the timer contents.
However, the two digits (10’s and units) of the minute,
hour and date items form a single item, so set both
digits when writing.
For example, to output an alarm at the same time
every day, it is only necessary to set the hour (both the
10’s and units digits) and minute (both the 10’s and
units digits) after executing an alarm reset. An alarm
reset clears the contents of the alarm register to “0”.
To compare “0” (to compare “0” for hour and minute,
for example, 00 hour, 00 minute), however, all items
enter the “don’t care” status when an alarm reset is
executed with alarms enabled and the ALARM signal
is output until an alarm is set. Because of that, it is
necessary to disable alarms before executing an alarm
reset.

INTALARM (Internal)
As with ALARM signal output, interrupts can be generated
with any of the three following signals. 1) Comparator
output, 2) 1Hz, 3) 16Hz.
Interrupts are generated internally in synchronization
with falls of the ALARM pin output.
INTALARM is reset by system resets (when RESET =
“Low”).
