Enable:
This READ/WRITE bit-field permits the user to either
enable or disable the "Change of FL Condition" Interrupt. If
the user enables this interrupt, then the XRT79L71 device
will generate an interrupt any time any of the following
events occur.
• Whenever the Jitter Attenuator (within XRT79L71)
declares the FL (FIFO Limit Alarm) condition.
• Whenever the Jitter Attenuator (within XRT79L71) clears
the FL (FIFO Limit Alarm) condition.
0 - Disables the "Change in FL Condition" Interrupt.
1 - Enables the "Change in FL Condition" Interrupt.
Change of Receive LOL (Loss of Lock) Condition Inter-

This READ/WRITE bit-field permits the user to either
enable or disable the "Change of Receive LOL Condition"
Interrupt. If the user enables this interrupt, then the
XRT79L71 device will generate an interrupt any time any of
the following events occur.
• Whenever the Receive Section (within XRT79L71)
declares the "Loss of Lock" Condition.
• Whenever the Receive Section (within XRT79L71) clears
the "Loss of Lock" Condition.
