0 = When RX direction OOF occurs,
do not insert AIS-L.
1 = When RX direction OOF occurs, insert AIS-L.
0 = Do not force AIS-L insert
1 = Always force AIS-L insert
0 = Do not insert a parity error
1 = Insert parity error in parity bit of receive TOH serial out-
put for as long as this bit is set
0 = Set receive direction K1 K2 bytes to 0.
1 = Pass receive direction K1 K2 through pointer mover.
0 = Do not insert parity error.
1 = Insert parity error in DOUTxx_PAR for as long as this
bit is set.
0 = Power down CDR channels
1 = Functional mode.

1 = Pass through S1 M0 of DINxx
0 = Insert E1, F1, E2 from TOH_INxx on FPGA interface
1 = Pass through E1, F1, E2 TOH bytes of DINxx
0 = Insert TOH from TOH_INxx on FPGA interface for
transmit
1 = Pass through all TOH DINxx for transmit
0 = Insert TOH for transmit from TOH_INxx from the FPGA
interface.
1 = Pass through D1~D8 TOH bytes from DINxx.
