Per-minute edge interrupt output
Per-minute edge interrupt output is the function to output “L” from the
1
INT /
2
INT
pin, when the first minute-carry
processing is done, after selecting the output mode.
To set the pin output to “H”, turn off the output mode of per-minute edge interrupt. In the
1
INT
pin output mode, input
“0” in INT1ME in the status register 2. In the
2
INT
pin output mode, input “0” in INT2ME.

"L" is output again if this period is within 7.9 ms

INT2 pin output mode
INT2AE = Don’t care (0 or 1), INT2FE = 0
*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
1
INT /
2
INT
pin, when the first minute-carry processing is done, after selecting the output mode.

pin is in “L”.
Note that pin output is set to “L” by setting enable the output mode again.
