Change in Out of Frame Defect Condition interrupt enable
This bit permits the user to either enable or disable the “Change in Out of
Frame Defect Condition” Interrupt, within the XRT86VL32 device. If the
user enables this interrupt, then the Receive E1 Framer block will generate
an interrupt in response to either one of the following conditions.
1.
The instant that the Receive E1 Framer block declares the Out of
Frame defect condition.
2.
The instant that the Receive E1 Framer block clears the Out of
Frame defect condition.
0 – Disables the “Change in Out of Frame Defect Condition” Interrupt.
1 – Enables the “Change in Out of Frame Defect Condition” Interrupt.

Frame Mimic Detection Interrupt Enable
This bit permits the user to either enable or disable the “Frame Mimic
Detection” Interrupt, within the XRT86VL32 device. If the user enables this
interrupt, then the Receive E1 Framer block will generate an interrupt
when it detects the presence of Frame mimic bits (i.e., the payload bits
have appeared to mimic the framing bit pattern within the incoming E1
data stream).
0 – Disables the “Frame Mimic Detection” Interrupt.
1 – Enables the “Frame Mimic Detection” Interrupt.

Synchronization Bit (CRC-4) Error Interrupt Enable
This bit permits the user to either enable or disable the “CRC-4 Error
Detection” Interrupt, within the XRT86VL32 device. If the user enables this
interrupt, then the Receive E1 Framer block will generate an interrupt
when it detects a CRC-4 error within the incoming E1 sub-multiframe.
0 – disable the “CRC-4 Error Detection” Interrupt.
1 – enable the “CRC-4 Error Detection” Interrupt.

Framing Bit Error Interrupt Enable
This bit permits the user to either enable or disable the “Framing Alignment
Bit Error Detection” Interrupt, within the XRT86VL32 device. If the user
enables this interrupt, then the Receive E1 Framer block will generate an
interrupt when it detects one or more Framing Alignment Bit error within
the incoming E1 data stream.
0 – disable the “Framing Alignment Bit Error Detection” Interrupt.
1 – enable the “Framing Alignment Bit Error Detection” Interrupt.

:
Detecting Framing Alignment Bit Error doesn't not necessarily
indicate that synchronization has been lost.
