5. Minute-periodical interrupt output 2 (only in the
1
INT
pin output mode)
The output of minute-periodical interrupt 2 is the function to output “L”, for 7.9 ms, from the
1
INT
pin, synchronizing with
the first minute-carry processing after selecting the output mode. However, in Read in the real-time data register, the
procedure delays at max. 0.5 sec thus output “L” from the
1
INT
pin also delays at max. 0.5 sec. In Write in the real-time
data register, some delay is made in the output period due to Write timing and the second-data during Write.
