(5) Procedure for Format7
a) Aquire the available mode for Format7.
As bit 0 is set, it means that mode 0 is available.
b) Acquire the CSR offset address of Mode0.
F0000000h + (00400040h ∗ 4) = F1000100h
It means that the offset address of Video Mode CSR for Format7_Mode0 is F1000100h.
c) Acquire the MaxSize/UnitSize/ColorCodingID.
It means that MaxSize is 1,280 × 960, UnitSize is 320 × 240, ColorCodingID is YUV 4 : 2 : 2 for the DFW-SX900.
It means that MaxSize is 1,024 × 768, UnitSize is 512 × 192, ColorCodingID is YUV 4 : 2 : 2 for the DFW-X700.
d) Set the ImagePosition/ImageSize/ColorCodingID.
The DFW-SX900 is described as an example.
NOTE
: For YUV 4 : 2 : 2, write 02000000h for ColorCodingID.
Take note that this can be easily mistaken for the previously mentioned ColorCodingID
20000000h.
