Framing Bit Error Interrupt Enable

This bit permits the user to either enable or disable the âFraming

Alignment Bit Error Detectionâ Interrupt, within the XRT86SH328

device. If the user enables this interrupt, then the Receive T1

Framer block will generate an interrupt when it detects one or more

Framing Alignment Bit error within the incoming T1 data stream.

0 - Disables the âFraming Alignment Bit Error Detectionâ Interrupt.
