DPGWDTH<1:0>: STN Display Glass Data Width bits
11 = Reserved
10 = 16 bits wide
01 = 8 bits wide
00 = 4 bits wide
These bits have no effect on TFT mode. TFT display glass data width is always assumed to be 16 bits wide.
DPSTGER<1:0>: Display Data Timing Stagger bits
11 = Delays of the display data are staggered in groups:
10 = Even bits of the display data are delayed by 1 full GPUCLK cycle; odd bits are not delayed
01 = Odd bits of the display data are delayed by ½ GPUCLK cycle; even bits are not delayed
00 = Display data timing is all synchronized on one clock GPUCLK edge
Unimplemented: Read as ‘0’
DPTEST<1:0>: Display Test Pattern Generator bits
11 = Borders
10 = Bars
01 = Black screen
00 = Normal Display mode; test patterns are off
DPBPP<2:0>: Display bits-per-pixel Setting bits
This setting must match the GPU bits-per-pixel set in PUBPP<2:0> (G1CON1<7:5>).
100 = 16 bits-per-pixel
011 = 8 bits-per-pixel
010 = 4 bits-per-pixel
001 = 2 bits-per-pixel
000 = 1 bit-per-pixel
Other = Reserved
Unimplemented: Read as ‘0’
DPMODE<2:0>: Display Glass Type bits
011 = Color STN type
010 = Mono STN type
001 = TFT type
000 = Display off
