DESCRIPTION
Transmit CMI Inversion:
This bit will flip the polarity of the transmit CMI data outputs at CMIP/N.
For debug use only.
Receive CMI Inversion:
This bit will flip the polarity of the receive CMI data inputs at RXP/N. For
debug use only.
Receive Loss of Signal Override/Disable:
When set, the LOS signal will always remain low.
Analog Loopback Selection:
RLBK
Reserved.
FIFO Reset:
This reset should be initiated anytime the transmitter or IC powers up to
ensure the FIFO is centered after internal VCO clocks and external
transmit clocks are stable.
DESCRIPTION
Reserved.
Transmit Fixed Equalizer Enable:
When enabled, compensates for between 0.75m and 1.5m of FR4 trace
to the LVPECL data inputs SIDP/N

Remote Loopback Enable: Recovered receive data
is looped back to the transmit driver for retransmission.
Local Loopback Enable: The transmit data is
looped back and used as the input to the receiver.
