10. Interrupt Operation
Two interrupt operations are available:
1) Alarm interrupt...........When a registered time for alarm (such as day-of-the-week, hour or minute) coincide with
calendar counter (such as day-of-the-week, hour or minute) interrupt to the CPU are
requested with INTR pin being “L” (ON).
2) Periodic interrupt ......The INTR pin comes to a “L” (ON) state every registered period outputting interrupt
request.
Function diagram of alarm and periodic interrupts are shown as follows:
10.1 Alarm Interrupt
For setting an alarm time, designated time such as day-of the week, hour or minute should be set to the alarm
registers being ALE bit to 0. After that set the ALE bit to 1, from this moment onward when such registered alarm
time coincide with the value of calendar counter the INTR comes down to “L” (ON). The INTR output can be con-
trolled by operating to the ALE and ALFG bits.
*1) Setting the ALC into 1 halt output of the alarm interrupt from INTR pin.
*2) Both of alarm and periodic interrupt can operate regardless of the state of CE pin, “H” or “L”.
*1) The “*” mark indicates the time when the registered alarm day-of-the-week and time coincide with calendar counter.
*2) Above figure describes in case of no periodic interruption.
*3) ALFG indicates a reverse state of INTR output.
