00 = Source FID (bit 0) out of the VCOMP is the same as the
respective bit from the Upstream Module
01 = Source FID (bit 0) out of the VCOMP is the inverse of the
respective bit from the Upstream Module
10 = Source FID (bit 0) out of the VCOMP is '0'.
11 = Source FID (bit 0) 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 0..
representing the Source Picture FID.. to be the same as the
Upstream Input.. the inverse of the Upstream Input.. programmably
set to '0'.. or programmably set to '1'.
