Phase of encoded colour subcarrier (including burst) relative to horizontal sync; can be
adjusted in steps of 360/256 degrees.
These are the 8 LSBs of the 9-bit code that selects the variable gain for the C
input representation in accordance with “ITU-R BT.601” ; see Table 33. The MSB is held
in subaddress 5DH; see Table 36.
GAINU = 2.17
