Alarm control register
When the alarm enable bit of the control/status register is
set (address 00, bit 2) the alarm control register
(address 08) is activated. All alarm, timer, and interrupt
output functions are controlled by the contents of the alarm
control register (see Fig.8).
7.6
Alarm registers
All alarm registers are allocated with a constant address
offset of hexadecimal 08 to the corresponding counter
registers (see Fig.4,Register arrangement).
An alarm signal is generated when the contents of the
alarm registers matches bit-by-bit the contents of the
involved counter registers. The year and weekday bits are
ignored in a dated alarm. A daily alarm ignores the month
and date bits. When a weekday alarm is selected, the
contents of the alarm weekday/month register will select
the weekdays on which an alarm is activated (see Fig.9).
Remark:
in the 12 h mode, bits 6 and 7 of the alarm hours
register must be the same as the hours counter.
