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.
