Reserved.
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when the input clock validity changes (from
‘valid’ to ‘invalid’ or from ‘invalid’ to ‘valid’), i.e., when the corresponding INn_DIFF bit (b5/4, 0DH) is ‘1’. Here n is 2 or 1.
0: Disabled. (default)
1: Enabled.
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when the input clock validity changes (from
‘valid’ to ‘invalid’ or from ‘invalid’ to ‘valid’), i.e., when the corresponding INn_CMOS bit (b3/2, 0DH) is ‘1’. Here n is 2 or 1.
0: Disabled. (default)
1: Enabled.
Reserved.
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’.
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’.
Reserved.
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’.
