*1.
If users clear INT1AE/INT2AE once; “L” is not output from the INT pin by setting INT1AE/INT2AE enable again, within
a period when the alarm time matches real-time data.
*2.
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 INT register 1.
Refer to “4. INT register 1 and INT register 2” in “ Configuration of Register”.
