– Setting the EMOn bit in combination with other
enable bits and a specific alarm time, the user can
establish an alarm that triggers at the same time
once a year.
When there is a match, an alarm flag is set. The occur-
ance of an alarm can be determined by polling the AL0
and AL1 bits, or by setting the AL0E and AL1E bits to
‘1’ and monitoring the IRQ output. The AL0E and AL1E
bits enable the circuit that triggers the output IRQ pin
when an alarm occurs. Writing a ‘0’ to one of the bits
disables the output IRQ for that alarm condition, but
the alarm condition can still be checked by polling the
alarm 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.
