Change in LOS Defect Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Change in LOS (Loss of Signal) Defect Condition
Interrupt, within the XRT79L71. If the user enables this interrupt,
then the Receive E3 Framer block will generate an interrupt in
response to either of the following conditions.
• The instant that the Receive E3 Framer block declares the
LOS defect condition.
• The instant that the Receive E3 Framer block clears the LOS
defect condition.
The Change in LOS Defect Condition Interrupt can be enabled
or disabled, as described below.
0 - Disables the Change in LOS Defect Condition Interrupt.
1 - Enables the Change in LOS Defect Condition Interrupt.
Change in AIS Defect Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
