ALARM REGISTERS
There are two alarm registers whose contents mimic the
contents of the RTC register, but add enable bits and
exclude the 24 hour time selection bit. The enable bits
specify which registers to use in the comparison between
the Alarm and Real Time Registers. For example:
– Setting the Enable Month bit (EMOn*) bit in combi-
nation with other enable bits and a specific alarm
time, the user can establish an alarm that triggers at
the same time once a year.
*n = 0 for Alarm 0: N = 1 for Alarm 1
When there is a match, an alarm flag is set. The occur-
rence of an alarm can be determined by polling the
AL0 and AL1 bits or by enabling the IRQ output, using
it as hardware flag.
The alarm enable bits are located in the MSB of the
particular register. When all enable bits are set to ‘0’,
there are no alarms.
– The user can set the X1288 to alarm every Wednes-
day at 8:00 AM by setting the EDWn*, the EHRn*
and EMNn* enable bits to ‘1’ and setting the DWAn*,
HRAn* and MNAn* Alarm registers to 8:00 AM
Wednesday.
– A daily alarm for 9:30PM results when the EHRn*
and EMNn* enable bits are set to ‘1’ and the HRAn*
and MNAn* registers are set to 9:30 PM.
*n = 0 for Alarm 0: N = 1 for Alarm 1
REAL TIME CLOCK REGISTERS
Clock/Calendar Registers (SSEC, SC, MN, HR, DT,
MO, YR)
These registers depict BCD representations of the
time. As such, SSEC (1/100 Second) range from 00 to
99, SC (Seconds) and MN (Minutes) range from 00 to
59, HR (Hour) is 1 to 12 with an AM or PM indicator
