From the viewpoint of software, the IRQ FLAG
bit is used.
From the viewpoint of hardware, pin 1 (PERIODIC OUT)
is used for the MSM6542-3 or pin 1 (INTERRUP OUT) for
the MSM6542-1/2.
*2
For the MSM6542-1/2, a signal resulting from the ORing
with output triggered by an alarm is output to pin 1. When
alarm factors are not required, the MASK
2
bit must be set
at 1.
*3
The IRQ FLAG
1
bit is cleared.
*1
From the viewpoint of software, the IRQ FLAG
bit is used.
From the viewpoint of hardware, pin 2 (ALARM OUT) is
used for the MSM6542-3 or pin 1 (INTERRUPT OUT) for
the MSM6542-1/2.
*2
For the MSM6542-1/2, a signal resulting from the ORing
with output triggered by a periodic carry is output to pin
1. When periodic factors are not required, 1 must be set
in the MASK
1
bit.
*3
Time required to delete the previous output factors in the
IC.
*4
The IRQ FLAG
2
bit is cleared.
