AMI:
The AMI bit enables AMI line coding. If AMI is set to a logic 1, the QDSX will
perform AMI line encoding on the TDD[X] single-rail input data stream. If AMI
is set to a logic 0, the QDSX will perform B8ZS (if the CEPT bit in register
001H, 041H, 081H, and 0C1H is set to logic 0) or HDB3 (if the CEPT bit is
set to logic 1) line encoding on the TDD[X] single-rail input data stream. The
AMI bit has no function if the TDUAL bit in the Transmit Configuration register
(001H, 041H, 081H, and 0C1H) or if the TDUAL input pin is set to logic 1.
