3. Per-minute edge interrupt output
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.

INT pin
OFF
"L" is output again if this period is within 7.9 ms*1.

32kE = 0, INT1AE = Don’t care (0 or 1), INT1FE = 0

Pin output is set to “H” by disabling the output mode within 7.9 ms, because the signal of this procedure is maintained
for 7.9 ms. Note that pin output is set to “L” by setting enable the output mode again.

4. Minute-periodical interrupt output 1
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.

Setting the output mode disable makes the pin output “H”, while the output from the INT pin is in “L”. Note that pin
output is set to “L” by setting enable the output mode again.
