4. INT1 register_1 and INT1 register_2
INT1 register_1 and INT1 register_2 are interrupt setting registers that can be set independently. The
interrupt is output from the INT pin under the OR condition of the two registers. INT1 register_1 allows
setting the alarm time or frequency duty. INT1 register_2 allows setting the alarm time. The function is
switched by using status register_2.
(1)
Alarm interrupt
Data set in INT1 register_1 and INT1 register_2 is considered as alarm time data. Having the
same configuration as the hour and minute registers of the real-time data register, these
registers represent hours and minutes with BCD codes. When setting these registers, do not set
any nonexistent day. Data to be set must be in accordance with the 12-hour or 24-hour
expression that is set in status register_1.

Figure 13 INT1 Register_1, INT1 Register_2 (Alarm Time Data)
In INT1 register_1, A1WE, A1HE, and A1mE are respectively in the MSB of each byte. By
setting each bit to “1”, the setting of the day of week data, hour data, and minute data in the
corresponding byte becomes valid. A2WE, A2HE, and A2mE of INT1 register_2 are the same.
