This bit indicates whether IN4 is in frequency hard alarm status.
0: No frequency hard alarm.
1: In frequency hard alarm status. (default)
This bit indicates whether IN4 is in no-activity alarm status.
0: No no-activity alarm.
1: In no-activity alarm status. (default)
This bit indicates whether IN4 is in phase lock alarm status.
0: No phase lock alarm. (default)
1: In phase lock alarm status.
If the PH_ALARM_TIMEOUT bit (b5, 09H) is ‘0’, this bit is cleared by writing ‘1’ to this bit; if the
PH_ALARM_TIMEOUT bit (b5, 09H) is ‘1’, this bit is cleared after a period (= TIME_OUT_VALUE[5:0] (b5~0,
08H) X MULTI_FACTOR[1:0] (b7~6, 08H) in second) which starts from when the alarm is raised.
