Interrupts
The INT pin output mode is selected by the INT2AE, INT1AE, INT1ME, and INT1FE flags of status
register_2. Note that when INT2AE is enabled, if the alarm 2 interrupt occurs, low is output from the INT pin
regardless of the settings of the INT1AE, INT1ME, and INT1FE flags.
(1) Alarm interrupt output
When the INT pin output mode is set as the alarm setting using status register_2 and the day of week,
hour, and minute data is set in INT1 register_1 (or INT1 register_2), low is output from the INT pin
when the set hour is reached. Since the output is held, rewrite INT1AE of status register_2 to “0” (or
INT2AE to “0”) using serial communication to set the output to high (OFF state).
