Per-minute edge interrupt output
Per-minute edge interrupt output is the function to output “L” from the
2
INT
pin, when the first minute-carry processing
is done, after selecting the output mode.
To set the pin output to “H”, in the
2
INT
pin output mode, input “0” in INT2ME in the status register 2 in order to turn off
this mode.

*1. 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.

Minute-periodical interrupt output 1
The minute-periodical interrupt 1 is the function to output the one-minute clock pulse (Duty 50%) from the
2
INT
pin,
when the first minute-carry processing is done, after selecting the output mode.
