Figure 7: Time of Pre-minute Steady Interrupt Output2

Caution:

1.If Per-minute edge interrupt output mode or Per-minute steady interrupt mode is chosen, there is no

difference between INT1 register_1 register_2.

2.When the output mode is changed, take care to the state of INT1 regisert_1 or register_2 and the output

6.5.6 During Power-on Detector Operation

When power is applied to this IC, power-on detection circuit operates, status register_1 is set to “80h” (bit 7

(POC flag) of status register_1 is set to 1) via the power-on detection circuit, and a 1 Hz clock is output from the

INT1# pin.
