DESCRIPTION
R/O
R/W 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
Receive LOL Condition Interrupt. If the user enables this interrupt, then the
XRT73R12 will generate an interrupt any time any of the following events
occur.
• Whenever the Receive Section (within Channel n) declares the Loss of
Lock Condition.
• Whenever the Receive Section (within Channel n) clears the Loss of Lock
Condition.
0 - Disables the Change in Receive LOL Condition Interrupt.
1 - Enables the Change in Receive LOL Condition Interrupt.
R/W Change of the Receive LOS (Loss of Signal) Defect Condition Interrupt
Enable - Ch 0:
This READ/WRITE bit-field is used to enable or disable the Change of the
Receive LOS Defect Condition Interrupt. If the user enables this interrupt,
then the XRT73R12 will generate an interrupt any time any of the following
events occur.
• Whenever the Receive Section (within Channel n) declares the LOS
Defect Condition.
• Whenever the Receive Section (within Channel n) clears the LOS Defect
condition.
0 - Disables the Change in the LOS Defect Condition Interrupt.
1 - Enables the Change in the LOS Defect Condition Interrupt.
R/W Change of Transmit DMO (Drive Monitor Output) Condition Interrupt
Enable - Ch n:
This READ/WRITE bit-field is used to enable or disable the Change of
Transmit DMO Condition Interrupt. If the user enables this interrupt, then
the XRT73R12 will generate an interrupt any time any of the following
events occur.
• Whenever the Transmit Section toggles the DMO output pin (or bit-field)
to "1".
• Whenever the Transmit Section toggles the DMO output pin (or bit-field)
to "0".
0 - Disables the Change in the DMO Condition Interrupt.
1 - Enables the Change in the DMO Condition Interrupt.
