BIT 7 - Change of Signal Failure (SF) Defect Condition Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Change of Signal Failure (SF) Defect Condition
Interrupt. If this interrupt is enabled, then the XRT86SH328 will generate an interrupt in response to any of the following
events.
Whenever the Receive STM-0 TOH Processor block declares the SF defect condition.
Whenever the Receive STM-0 TOH Processor block clears the SF defect condition.
0 - Disables the Change of SF Defect Condition Interrupt.
1 - Enables the Change of SF Defect Condition Interrupt.
BIT 6 - Change of Signal Degrade (SD) Defect Condition Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Change of Signal Degrade (SD) Defect Condition
Interrupt. If this interrupt is enabled, then the XRT86SH328 will generate an interrupt in response to either of the
following events.
Whenever the Receive STM-0 TOH Processor blolck declares the SD defect condition.
Whenever the Receive STM-0 TOH Processor block clears the SD defect condition.
0 - Disables the Change of SD Defect Condition Interrupt.
1 - Enables the Change of SD Defect Condition Interrupt.
BIT 5 - Detection of REI-L (Line - Remote Error Indicator) Event Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Detection of REI-L Event interrupt. If this interrupt is
enabled, then the XRT86SH328 will generate an interrupt anytime the Receive STM-0 TOH Processor block detects an
REI-L condition within the incoming STM-0 data-stream.
0 - Disables the Detection of REI-L Event Interrupt.
1 - Enables the Detection of REI-L Event Interrupt.
BIT 4 - Detection of B2 Byte Error Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Detection of B2 Byte Error Interrupt. If this interrupt
is enabled, then the XRT86SH328 will generate an interrupt anytime the Receive STM-0 TOH Processor block detects
a B2 byte error within the incoming STM-0 data-stream.
0 - Disables the Detection of B2 Byte Error Interrupt.
1 - Enables the Detection of B2 Byte Error Interrupt.
BIT 3 - Detection of B1 Byte Error Interrupt Enable:
This READ/WRITE bit-field is used to either enable or disable the Detection of B1 Byte Error Interrupt. If this interrupt
is enabled, then the XRT86SH328 will generate an interrupt anytime the Receive STM-0 TOH Processor block detects
a B1 byte error within the incoming STM-0 data-stream.
0 - Disables the Detection of B1 Byte Error Interrupt.
1 - Enables the Detection of B1 Byte Error Interrupt.
BIT 2 - Change of Loss of Frame (LOF) Defect Condition Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Change of LOF Defect Condition interrupt. If this
interrupt is enabled, then the XRT86SH328 will generate an interrupt in response to either of the following conditions
