Description
When the GPIO port is in SPI-16 input mode then this bit supplies
NTSC(0)/PAL(1) which selects the gamma ROM.
A value of 1 enables a color bars pattern at the input of the VDFC
block.
A value of 0 enables error diffusion for RGB16/RGB15 modes. A
value of 1 disables it.
A value of 0 enables gamma correction removal. The inverse
gamma correction factor of 2.2 or 2.8 is applied and auto-selected
by the respective mode NTSC/PAL. A value of 1 disables gamma
correction removal.
WordSwap Odd Field. A value of 1 enables word swapping of data
entering the FIFO. W2[31:16] swapped with W0[15:0]
WordSwap Even Field. A value of 1 enables word swapping of
data entering the FIFO. W2[31:16] swapped with W0[15:0]
ByteSwap Odd Field. A value of 1 enables byte swapping of data
entering the FIFO. B3[31:24] swapped with B2[23:16] and B1[15:8]
swapped with B0[7:0]
ByteSwap Even Field. A value of 1 enables byte swapping of data
entering the FIFO. B3[31:24] swapped with B2[23:16] and B1[15:8]
swapped with B0[7:0]
