Change of FL (FIFO Limit Alarm) Condition Interrupt Enable - Ch n:
This READ/WRITE bit-field is used to enable or disable the Change of FIFO
Limit Alarm Condition Interrupt. If the user enables this interrupt, the
XRT75R12D will generate an interrupt if any of the following events occur.
•
•
0 - Disables the Change in FL Condition Interrupt.
1 - Enables the Change in FL Condition Interrupt.
Change of Receive LOL (Loss of Lock) Condition Interrupt Enable -
Channel n:
This READ/WRITE bit-field is used to enable or disable the Change of
