Provide the status of the line counter.
Down count from LINEVAL to 0
Determine the rates of VCLK and CLKVAL[9:0].
STN: VCLK = HCLK / (CLKVAL
TFT: VCLK = HCLK / [(CLKVAL+1)
Determine the toggle rate of the VM.
0 = Each Frame,
1 = The rate defined by the MVAL
Select the display mode.
00 = 4-bit dual scan display mode (STN)
01 = 4-bit single scan display mode (STN)
10 = 8-bit single scan display mode (STN)
11 = TFT LCD panel
Select the BPP (Bits Per Pixel) mode.
0000 = 1 bpp for STN, Monochrome mode
0001 = 2 bpp for STN, 4-level gray mode
0010 = 4 bpp for STN, 16-level gray mode
0011 = 8 bpp for STN, color mode
0100 = 12 bpp for STN, color mode
1000 = 1 bpp for TFT
1001 = 2 bpp for TFT
1010 = 4 bpp for TFT
1011 = 8 bpp for TFT
1100 = 16 bpp for TFT
1101 = 24 bpp for TFT
LCD video output and the logic enable/disable.
0 = Disable the video output and the LCD control signal.
1 = Enable the video output and the LCD control signal.
