PERIODIC OUT (Only for the MSM6542-03)
This output pin is used for N-channel open drain. It outputs a single pulse or an
interrupt request as a trigger each time a carry is generated from the clock counter.
Output from this pin is not disabled by
CS
0
and CS
1
.
ALARM OUT (Only for the MSM6542-03)
This output pin is used for N-channel open drain. It outputs a single pulse or an
interrupt request each time the contents of the clock counter match the date and time for
which an alarm is set. Output from this pin is not disabled by
CS
0
and CS
1
.
INTERRUPT OUT (Only for the MSM6542-01/02)
This output pin is N-channel open drain. It ORs the signals from the PERIODIC OUT
and ALARM OUT pins above.
