= 0: Receiver power up
= 1: Receiver power down
= 0: data on RDn or RDPn/RDNn is active high
= 1: data on RDn or RDPn/RDNn is active low
= 0: data on RDn or RDPn/RDNn is updated on the rising edges of RCLKn
= 1: data on RDn or RDPn/RDNn is updated on the falling edges of RCLKn
= 00: receive data is HDB3 (E1) / B8ZS (T1/J1) decoded and output on RDn with single rail NRZ format
= 01: receive data is AMI decoded and output on RDn with single rail NRZ format
= 10: decoder is bypassed, re-timed dual rail data with NRZ format output on RDPn/RDNn (dual rail mode with
clock recovery)
= 11: both CDR and decoder blocks are bypassed, slicer data with RZ format output on RDPn/RDNn (slicer mode)
Reserved
= 0: receive equalizer off
= 1: receive equalizer on (LOS programming enabled)
Reserved. Should be 0 for normal operation.
