These bits represent a 2’s complement signed integer. If the value is multiplied by the value in the
FREQ_MON_FACTOR[3:0] bits (b3~0, 2EH), the frequency of an input clock with respect to the reference clock in ppm will
be gotten. The input clock is selected by the IN_FREQ_READ_CH[3:0] bits (b3~0, 41H).
The value in these bits is updated every 16 seconds, starting when an input clock is selected.

Reserved.
This bit indicates whether IN2 is in frequency hard alarm status.
0: No frequency hard alarm.
1: In frequency hard alarm status. (default)
This bit indicates whether IN2 is in no-activity alarm status.
0: No no-activity alarm.
1: In no-activity alarm status. (default)
This bit indicates whether IN2 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.
Reserved.
This bit indicates whether IN1 is in frequency hard alarm status.
0: No frequency hard alarm.
1: In frequency hard alarm status. (default)
This bit indicates whether IN1 is in no-activity alarm status.
0: No no-activity alarm.
1: In no-activity alarm status. (default)
This bit indicates whether IN1 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.
