Alarm Operation Examples
Following are examples of both Single Event and periodic
Interrupt Mode alarms.
EXAMPLE 1
Alarm 0 set with single interrupt (IM=”0”)
A single alarm will occur on January 1 at 11:30am.
A. Set Alarm 0 registers as follows:
B. Also the AL0E bit must be set as follows:
After these registers are set, an alarm will be generated when
the RTC advances to exactly 11:30am on January 1 (after
seconds changes from 59 to 00) by setting the AL0 bit in the
status register to “1”.
EXAMPLE 2
Pulsed interrupt once per minute (IM = ”1”)
Interrupts at one minute intervals when the seconds register
is at 30s.
A. Set Alarm 0 registers as follows:
B. Set the Interrupt register as follows:
Note that the status register AL0 bit will be set each time the
alarm is triggered, but does not need to be read or cleared.
