[Setting interrupt conditions]
Perfomr the following setting with the DP bit set at 0. The set values are independent of the
setting of the DP bit.
(a) Periodic interrupt output (*1)
(b) Alarm interrup output (*1)

*1
From the viewpoint of software, the IRQ FLAG
1
bit is used. From the viewpoint of hardware, pin
1 (PERIODIC OUT) is used for the MSM6542-
03 or pin 1 (INTERRUPT OUT) for the MSM6542-
01/02.
*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
2
bit is used. From the viewpoint of hardware, pin
3 (ALARM OUT) is used for the MSM6542-03
or pin 1 (INTERRUPT OUT) for the MSM6542-
01/02.
*2
For the MSM6542-01/02, 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 output the previous interrupt
factors
*4
The IRQ FLAG
2 bit is cleared.
