Pixel and I/O masking : By Mask at Write Per Bit Mode, the selected bit planes keep the original data.
By Pixel Data issued through DQ pin, the selected pixels keep the original data.
See PIXEL TO DQ MAPPING TANLE.
Assume 8bpp,
White = “0000,0000”, Red = “1010,0011”, Green = “1110,0001”, Yellow = “0000,1111”, Blue = “1100,0011”
i) STEP
SMRS (LCR) : Load color (for 8bpp, through X 32 DQ color0-3 are loaded into color registers)
Load (color3, color2, color1, color0) = (Blue, Green, Yellow, Red)
= “1100,0011,1110,0001,0000,1111,1010,0011”
SMRS (LMR) : Load mask, Mask[31-0] = “1111,1111,1101,1101,0100,0010,0111,0110”
→
Byte 3:No I/O Masking; Byte 2:I/O Masking; Byte 1:I/O and Pixel Masking; Byte 0:DQM Byte Masking
Row Active with DSF “H” : I/O Mask by Write Per Bit Mode Enable
Block Write with DQ[31-0] = “0111,0111,1111,1111,0101,0101,1110,1110”
