DESCRIPTION
Detection of CP-Bit Error Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the "Detection of CP-Bit Error" Interrupt, within the Chan-
nel. If the user enables this interrupt, then the Frame Synchro-
nizer block will generate an interrupt anytime it detects CP bit
errors.
0 - Disables the "Detection of CP Bit Error" Interrupt.
1 - Enables the "Detection of CP-Bit Error" Interrupt.
NOTE: This bit-field is ignored if the Frame Synchronizer block is
by-passed.
Change in LOS Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the "Change in LOS (Loss of Signal) 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 LOS condition.
• The instant that the channel clears the LOS condition.
0 - Disables the "Change in LOS Condition" Interrupt.
1 - Enables the "Change in LOS Condition" Interrupt.
Change in AIS Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the "Change in AIS (Alarm Indication Signal) 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 AIS condition.· The instant that the
channel clears the AIS condition.
0 - Disables the "Change in AIS Condition" Interrupt.
1 - Enables the "Change in AIS Condition" Interrupt.
NOTE: This bit-field is ignored if the Frame Synchronizer block is
by-passed.
