LCDDUAL
Single or Dual LCD panel selection.
STN LCD interface is:
0 = single-panel.
1 = dual-panel.
0x0
8
BGR
Color format selection.
0 = RGB: normal output.
1 = BGR: red and blue swapped.
0x0
9
BEBO
Big-endian Byte Order.
Controls byte ordering in memory:
0 = little-endian byte order.
1 = big-endian byte order.
0x0
10
BEPO
Big-Endian Pixel Ordering.
Controls pixel ordering within a byte:
0 = little-endian ordering within a byte.
1 = big-endian pixel ordering within a byte.
The BEPO bit selects between little and big-endian pixel packing
for 1, 2, and 4 bpp display modes, it has no effect on 8 or 16 bpp
pixel formats.
See Pixel serializer for more information on the data format.
0x0
11
LCDPWR
LCD power enable.
0 = power not gated through to LCD panel and LCDV[23:0]
signals disabled, (held LOW).
1 = power gated through to LCD panel and LCDV[23:0] signals
enabled, (active).
See LCD power-up and power-down sequence for details on
LCD power sequencing.
0x0

LCDVCOMP
LCD Vertical Compare Interrupt.
Generate VComp interrupt at:
00 = start of vertical synchronization.
01 = start of back porch.
10 = start of active video.
11 = start of front porch.
0x0

WATERMARK LCD DMA FIFO watermark level.
Controls when DMA requests are generated:
0 = An LCD DMA request is generated when either of the DMA
FIFOs have four or more empty locations.
1 = An LCD DMA request is generated when either of the DMA
FIFOs have eight or more empty locations.
