Bit
Name
Description
7
EX_SYNC_ALARM
This bit indicates whether an external sync alarm is raised; i.e., whether there is a transition from ‘0’ to ‘1’ on the
EX_SYNC_ALARM_MON bit (b7, 52H).
0: Has not occurred.
1: Has occurred. (default)
This bit is cleared by writing a ‘1’.
6T4_STS
This bit indicates the T4 DPLL locking status changes (from ‘locked’ to ‘unlocked’ or from ‘unlocked’ to ‘locked’); i.e., whether
there is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the T4_DPLL_LOCK bit (b6, 52H).
0: Has not changed.
1: Has changed. (default)
This bit is cleared by writing a ‘1’.
5
-
Reserved.
4INPUT_TO_T4
This bit indicates whether all the input clocks for T4 path changes to be unqualified; i.e., whether the
HIGHEST_PRIORITY_VALIDATED[3:0] bits (b7~4, 4EH) are set to ‘0000’ when these bits are available for T4 path.
0: Has not changed.
1: Has changed. (default)
This bit is cleared by writing a ‘1’.
3AMI2_VIOL
This bit indicates whether IN2 has an AMI violation.
0: Has no AMI violation. (default)
1: Has an AMI violation.
This bit is cleared by writing a ‘1’.
2
AMI2_LOS
This bit indicates whether IN2 has a LOS error.
0: Has no LOS error. (default)
1: Has a LOS error.
This bit is cleared by writing a ‘1’.
1AMI1_VIOL
This bit indicates whether IN1 has an AMI violation.
0: Has no AMI violation. (default)
1: Has an AMI violation.
This bit is cleared by writing a ‘1’.
0
AMI1_LOS
This bit indicates whether IN1 has a LOS error.
0: Has no LOS error. (default)
1: Has a LOS error.
This bit is cleared by writing a ‘1’.
