If users clear INT1AE/INT2AE once; “L” is not output from the
1

INT
pin by setting INT1AE/INT2AE enable again,
within a period when the alarm time matches real-time data.

If turning the alarm output on by changing the program, within the period when the alarm time matches real-time data,
“L” is output again from the

INT
pin when the minute is counted up.

2. Output of user-set frequency
The output of user-set frequency is the function to output the frequency which is selected by using data, from the

INT
pin, in the AND-form. Set up the data of frequency in the INT1/INT2 register.
Refer to “4. INT1 register and INT2 register” in “ Configuration of Register”.
