00 = Encoder FID (bit 1) out of the VCOMP is the same as the
respective bit from the Upstream Module
01 = Encoder FID (bit 1) out of the VCOMP is the inverse of the
respective bit from the Upstream Module
10 = Encoder FID (bit 1) out of the VCOMP is '0'.
11 = Encoder FID (bit 1) out of the VCOMP is '1'.
When both the Main and Aux sources are enabled.. NF and the
Source/Encoder FID values are taken from the Main or Aux ports as
defined in cfg_nf_handling. Otherwise.. NF and the Source/Encoder
FID values are taken from the Active port. In no plane is active.. then
no NF will be sent downstream. This register setting enables Bit 1..
representing the Encoder FID.. to be the same as the Upstream
Input.. the inverse of the Upstream Input.. programmably set to '0'..
or programmably set to '1'.
