INT1 register and INT2 register
The INT1 register is to set up the alarm time. The INT2 register is to set up the output of user-set frequency or alarm
interrupt. To switch the output mode, use the status register 2.
The INT1 register works as an alarm-time data register in the alarm 1 interrupt mode selected by users. The INT1 flag
(B3 in the status register) displays the alarm time when it matches.
The INT2 register works as an alarm-time data register in the alarm interrupt mode selected by using the status register
2. In the mode output of user-set frequency, the INT2 register works as a data register to set up the frequency for output
clock. Clock pulse and output of alarm interrupt are output from the
2
INT
pin. And the INT2 flag (B2 in the status
register) displays the alarm time when it matches.

Alarm interrupt
Users can set the alarm time (the data of day of the week, hour, minute) by using the INT1 and INT2 registers which
are 3-byte data registers. The configuration of register is as well as the data register of day of the week, hour, minute,
in the real-time data register; is expressed by the BCD code. Do not set a nonexistent day. Users are necessary to
set up the alarm-time data according to the 12/24 hour expression that they set by using the status register 1.

INT1 Register and INT2 Register (Alarm-Time Data)
The INT1 register has A1WE, A1HE, A1mE at B0 in each byte. It is possible to make data valid; the data of day of
the week, hour, minute which are in the corresponded byte; by setting these bits to “1”. This is as well in A2WE,
A2HE, A2mE in the INT2 register.
Setting example: alarm time “7:00 pm” in the INT1 register
(a) 12-hour expression (status register 1
B6 = 0)
