OEP—Output Enable Polarity
0 = The LCD_AC/LOE pin polarity is active high.
1 = The LCD_AC/LOE pin polarity is active low.
HSP—Horizontal Sync Polarity
0 = The LOAD/HSYNC pin polarity is active high.
1 = The LOAD/HSYNC pin polarity is active low.
VSP—Vertical Sync Polarity
0 = The FRAME/VSYNC pin polarity is active high.
1 = The FRAME/VSYNC pin polarity is active low.
DP—Data Polarity
0 = The LCD data (LD) pin polarity is active high.
1 = The LCD data (LD) pin polarity is active low.
BPIX—Bits Per Pixel
This field indicates the number of bits that represent one pixel in display memory.
00 = One bit per pixel.
01 = Two bits per pixel.
10 = Four bits per pixel.
11 = Eight bits per pixel.
LBW—LCD Bus Width
This field indicates the number of data bits that are output for every SHIFT/CLK. It is only
valid for passive displays. For TFT displays, see the TFT bit below.
0 = Four bits per clock.
1 = Eight bits per clock.
SPLT—Split Display Mode
0 = The display is single-scan (one row is displayed at a time).
1 = The display is dual-scan (two rows are displayed at a time).
CLOR—Color Display
0 = The LCD panel is a monochrome display.
1 = The LCD panel is a color display.
TFT—TFT Display
When this bit is set, 12 bits of RGB (4 bits per color) data are provided on the LD data bus.
0 = The LCD panel is a passive display.
1 = The LCD panel is an active (TFT) display.
