RXDINV:

The RXDINV bit selects the active polarity of the RXD+/- signals. The default configuration selects RXD+ to be active high and RXD- to be active low. When RXDINV is set to logic one, RXD+ to be active low and RXD- to be active high.

TFPI_EN:

The TFPI_EN bit controls the framing alignment in the transmit direction. When TFPI_EN is set to logic one the transmit SONET/SDH framing is aligned to a master (available to all four channels) framing pulse counter, which can also be aligned to the TFPI device input. When TFPI_EN is set to logic zero the transmit framing alignment is arbitrary. External framing (TFPI_EN set to logic one) shall only be used when the channel is in self- timed mode. TFPI_EN should always be set to logic zero when the channel is loop-timed (LOOPT set to logic one) or in line loopback (LLE set to logic one).
