NOTE(S):
1. RGB digital input denotes that the CX25870/871 will be configured to receive the RGB default pixel input mode after an
2. YCrCb digital input' denotes that the CX25870/871 will be configured to receive YCrCb pixel data after an autoconfiguration
3. CX25870/871 registers not listed in this table (including IN_MODE[3:0]) do not get reprogrammed as a result of an
4. Pixel or Character signifies that this overscan ratio is acceptable for 8-clock per character graphics controllers or pixel-clock
5. The CX25870/871 will be in master interface immediately after any autoconfiguration mode EXCEPT Mode 28 and Mode 29.
6. Mode 44 would ideally have 858 clocks per line. However, since 858 is not a multiple of 8, then 880 clocks per line was
