DESCRIPTION
7 to 0
CHPS[7:0]
Phase of encoded colour subcarrier (including burst) relative to horizontal sync; can be
adjusted in steps of 360/256 degrees.
0FH = PAL-B/G and data from input ports
3AH = PAL-B/G and data from look-up table
35H = NTSC-M and data from input ports
57H = NTSC-M and data from look-up table

DESCRIPTION
7 to 0
GAINU[7:0]
These are the 8 LSBs of the 9-bit code that selects the variable gain for the C
B
signal;
input representation in accordance with “ITU-R BT601” see Table 33. The MSB is held
in subaddress 5DH; see Table 36.
