3. Per-minute edge interrupt output
4. Minute-periodical interrupt output 1
Per-minute edge interrupt output is the function to output “L” from the INT pin, when the first minute-carry processing is
done, after selecting the output mode. To set the pin output to “H”, set “0” in INT1ME in the status register 2 to turn off the
output mode of per-minute edge interrupt.
*1. Pin output is set to “H” by disabling the output mode within 7.9 ms, because the signal of this procedure is maintained
The minute-periodical interrupt 1 is the function to output the one-minute clock pulse (Duty 50%) from the INT pin, when
the first minute-carry processing is done, after selecting the output mode.
*1. Setting the output mode disable makes the pin output “H”, while the output from the INT pin is in “L”. Note that pin
