Real Time Clock (RTC)
12.10.6 Alarm Minute and Hour Registers (ALMR and ALHR)
Data Sheet
240
NOTE:
NOTE:
Address:
Address:
These read/write registers contain the alarm minute and hour values for
the hour and minute alarm function. When the hour counter matches the
value in the alarm hour register (ALHR) and the minute counter matches
the value in the alarm minute register (ALMR), the alarm flag, ALMF, is
set. When ALMF is set and the alarm interrupt enable bit, ALMIE, is also
set, a CPU interrupt request is generated.
Writing values other than 0 to 59, to ALMR is possible, but the alarm flag
will never be set.
Writing values other than 0 to 23, to ALHR is possible, but the alarm flag
will never be set.
