4 | VIDC base mode (default for parameters not explicitly specified) | |
4 | VIDC parameter (repeat as required) | |
4 | -1 (terminator) | |
4 | Extended VIDC parameter (repeat as required) | |
4 | -1 (terminator) |
n | Value | Bit | Meaning when set | Default |
---|---|---|---|---|
0 | Pixel rate (kHz) | 24 MHz | ||
1 | Sync polarity | 0 | HSync –ve (else +ve) | +ve |
1 | VSync –ve (else +ve) | +ve | ||
2 | VIDC clock rate (kHz) |
VIDC extended parameters are encoded as (n << 24 OR value)
