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 XRT75R12 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.

Transmit DMO Condition Interrupt. If the user enables this interrupt, then

the XRT75R12 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".
