Receive Bipolar Violation Interrupt Enable:
When this bit is set to 0:
The Receive Bipolar Violation interrupt is disabled. Occurrence
of one or more bipolar violations will not generate an interrupt.
When this bit is set to 1:
The Receive Bipolar Violation interrupt is enabled. Occurrence
of one or more bipolar violations will generate an interrupt.
Receive Red Alarm State Change Interrupt Enable:
When this bit is set to 0:
The Receive Red Alarm State Change interrupt is disabled. No
Receive Loss of Frame (RxLOF) interrupt will be generated upon
detection of LOF condition.
When this bit is set to 1:
The Receive Red Alarm State Change interrupt is enabled.
Receive Loss of Frame (RxLOF) interrupt will be generated upon
detection of LOF condition.
Receive AIS State Change Interrupt Enable:
When this bit is set to 0:
The Receive AIS State Change interrupt is disabled.
When this bit is set to 1:
The Receive AIS State Change interrupt is enabled.
Receive Yellow Alarm State Change Interrupt Enable:
When this bit is set to 0:
The Receive Yellow Alarm State Change interrupt is disabled.
Any state change of Receive Yellow Alarm will not generate an
interrupt.
When this bit is set to 1:
The Receive Yellow Alarm State Change interrupt is enabled.
Any state change of Receive Yellow Alarm will generate an inter-
rupt.
