(5) Per-minute steady interrupt output 2
When the first minute carry is performed after the INT pin output mode is set as per-minute steady
interrupt 2 using status register_2, low is output from the INT pin for a period of 7.9 ms in
synchronization with the minute carry processing inside the IC. However, when real-time data is read,
the minute carry processing is delayed by a maximum of 0.5 s and accordingly low output from the INT
pin is also delayed by a maximum of 0.5 s. When the second data is rewritten by a real-time data write
command, counting starts from the rewritten second data and as a result, the output interval during that
period may become either longer or shorter.

Caution 1. When changing an output mode, give care to the state of INT1 register_1 and the
output.
2. If per-minute edge interrupt output or per-minute steady interrupt output is chosen,
INT1 register_1 has no meaning.
