Note
In the above typical operation, alarm time (hour and minute) is collated with
clock time by making interrupt operation a maximum of 37 times per day as
shown by the following calculation:
23(1-hour digit)+5(10-minute digit)+9(1-minute digit)=37 times
In this connection, a total current consumption increase resulting from inter-
rupt operation can also be calculated as follows:
Assuming, for example, that interrupt operation to the CPU takes 50 ms and
consumes 10mA of current, an average current consumption increase result-
ing from interrupt operation can be calculated as follows: (50 ms

times) / (60 seconds

24 hours)=0.21μA Counting in a standard
current consumption of about 0.91μA when the RS5C313 is set to 3V, a total
current consumption can be calculated at about 1.1μA.
*
1) In this typical operation, alarm time is stored in the CPU and collated with
clock time through interrupt operation.
*
2) Initially set address h to Ch (every 1 hour) and change it in the following
sequence for every matching of clock counter readings in
Ch

In this manner, change the settings of the interrupt cycle register.

3) Write 2h for the 12-hour format or 6h for the 24-hour format.

4) Collate alarm time with clock time through interrupt operation.
