32-kHz clock pulses are output from the INTRB pin.
· When more than one output wave forms are output from a single output pin, the output will have OR wave form of
negative logic of both.
Example: When Alarm_A and Alarm_B are output from the INTRA pin.
Alarm_A
Alarm_B
INTRA
In such a case which output wave form is output from the pin may be confirmed by reading
the flag register.
4.1-2 Alarm Interrupt (RS5C372A)
For setting an alarm time, designated time such as day-of-the-week, hour or minute should be set to the alarm regis-
ters being AALE (BALE) bit to 0. After that set the AALE (BALE) bit to 1, from this moment onward when such
registered alarm time coincide the value of calendar counter the INTRA or INTRB comes down to “L” (ON). The
INTRA or INTRB output can be controlled by operating to the AALE (BALE) and AAFG (BAFG) bits.
