Color DTO reset:
0 = Color subcarrier DTO not reset. (default)
1 = Color subcarrier DTO reset
Color subcarrier DTO is reset to zero and the color subcarrier DTO bit then immediately returns to zero.
When this bit is set, the subcarrier DTO phase reset bit is transmitted on the GCLO terminal on the next occurrence
of a specified line (NTSC or PAL).
Automatic color gain control:
00 = ACC enabled (default)
01 = Reserved
10 = ACC disabled
11 = ACC frozen
