(3) Per-minute edge interrupt output
When the first minute carry is performed after the INT pin output mode is set as the per-minute edge
interrupt using status register_2, low is output from the INT pin. Since the output is held, rewrite 32kE,
INT1AE, INT1ME, and INT1FE of status register_2 to “0” using serial communication to set the output
to high (OFF state).

“L” signal is output again
if 123
s or less.

Caution Since the minute carry processing signal is retained for 123
s, if communication disable
or enable is executed during this period, low is output from the INT pin again.
(4) Per-minute steady interrupt output 1
When the first minute carry is performed after the INT pin output mode is set as per-minute steady
interrupt 1 using status register_2, a clock whose cycle is 1 minute (50% duty) is output from the INT
pin.
