Change of Idle Condition
Interrupt Enable
R/W
Change in Idle Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the "Change in Idle Condition" Interrupt, within the Chan-
nel. If the user enables this interrupt, then the Frame Synchro-
nizer block will generate an interrupt in response to either of the
following conditions.
The instant that the channel detects the Idle condition.
The instant that the channel ceases to detect the Idle
condition.
0 - Disables the "Change in Idle Condition" Interrupt.
1 - Enables the "Change in Idle Condition" Interrupt.
N
OTE
:
This bit-field is ignored if the Frame Synchronizer block is
by-passed.
3
Change of FERF
Condition Interrupt
Enable
R/W
Change in FERF Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the "Change in FERF (Far-End Receive Failure) Condi-
tion" Interrupt, within the Channel. If the user enables this inter-
rupt, then the Frame Synchronizer block will generate an
interrupt in response to either of the following conditions.
The instant that the channel declares an FERF condition.
The instant that the channel clears the FERF condition.
0 - Disables the "Change in FERF Condition" Interrupt.
1 - Enables the "Change in FERF Condition" Interrupt.
N
OTE
:
This bit-field is ignored if the Frame Synchronizer block is
by-passed.
2
Change of AIC State
Interrupt Enable
R/W
Change in AIC State Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the "Change in AIC State" Interrupt, within the Channel.
If the user enables this interrupt, then the Frame Synchronizer
block will generate an interrupt in response to it detecting a
change in the AIC bit-field, within the incoming DS3 data stream.
N
OTE
:
This bit-field is ignored if the Frame Synchronizer block is
by-passed.
1
Change of OOF
Condition Interrupt
Enable
R/W
Change in OOF Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the "Change in OOF (Out of Frame) Condition" Interrupt,
within the Channel. If the user enables this interrupt, then the
Frame Synchronizer block will generate an interrupt in response
to either of the following conditions.
The instant that the channel declares an OOF condition.
The instant that the channel clears the OOF condition.
0 - Disables the "Change in OOF Condition" Interrupt.
1 - Enables the "Change in OOF Condition" Interrupt.
N
OTE
:
This bit-field is ignored if the Frame Synchronizer block is
by-passed.
