SETCMOD sets the CMOD register. This register has 9 bits that control the general behaviour of the colorspace converter:
| Bits | Function |
|---|---|
| 0 | Sync polarity invert (mode 01 only) |
| 1 | Add DAC0 into Y term |
| 2 | Add DAC0 into I term |
| 3 | Add DAC0 into Q term |
| 4 | Sign-extend coefficents (zero-extend otherwise) |
| 6:5 | Mode selection |
| 7 | Reverse TMDS pin order |
| 8 | Enable TMDS mode (replaces pin outputs) |
TODO explain modes.
