Checkerboa Scale Checkered Patterns:
rd Scale 0: Normal operation (each square is 1x1 pixel)
(default)
1: Scale checkered patterns (VCOM and
checkerboard) by 8 (each square is 8x8 pixels)
Setting this bit gives better visibility of the checkered
patterns.
5
RW
Custom
Use Custom Checkerboard Color
Checkerboa 0: Use white and black in the Checkerboard pattern
rd
(default)
1: Use the Custom Color and black in the
Checkerboard pattern

PG 18–bit
Mode
18-bit Mode Select:
0: Enable 24-bit pattern generation. Scaled patterns
use 256 levels of brightness. (default)
1: Enable 18-bit color pattern generation. Scaled
patterns will have 64 levels of brightness and the R,
G, and B outputs use the six most significant color
bits.

RW
External
Clock
Select External Clock Source:
0: Selects the internal divided clock when using
internal timing (default)
1: Selects the external pixel clock when using internal
timing. This bit has no effect in external timing mode
(PATGEN_TSEL = 0).
2
RW
Timing
Select
Timing Select Control:
0: the Pattern Generator uses external video timing
from the pixel clock, Data Enable, Horizontal Sync,
and Vertical Sync signals. (default)
1: The Pattern Generator creates its own video timing
as configured in the Pattern Generator Total Frame
Size, Active Frame Size. Horizontal Sync Width,
Vertical Sync Width, Horizontal Back Porch, Vertical
Back Porch, and Sync Configuration registers.

RW
Color Invert
Enable Inverted Color Patterns:
0: Do not invert the color output. (default)
1: Invert the color output.

RW
Auto Scroll
Auto Scroll Enable:
0: The Pattern Generator retains the current pattern.
(default)
1: The Pattern Generator will automatically move to
the next enabled pattern after the number of frames
specified in the Pattern Generator Frame Time
(PGFT) register.
