Change by program
*1. If users clear INT2AE once; “L” is not output from the
2
INT
pin by setting 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
2
INT
pin when the minute is counted up.

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
2
INT
pin, in the AND-form. Set up the data of frequency in the INT2 register.
