18 Bits
18-bit Mode Select
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.
0: Enable 24-bit pattern generation. Scaled patterns
use 256 levels of brightness.

Generator
External
Clock
Select External Clock Source
1: Selects the external pixel clock when using internal
timing.
0: Selects the internal divided clock when using internal
timing
This bit has no effect in external timing mode
(PATGEN_TSEL = 0).

Generator
Timing
Select
Timing Select Control
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.
0: the Pattern Generator uses external video timing
from the pixel clock, Data Enable, Horizontal Sync, and
Vertical Sync signals.
Pattern
Enable Inverted Color Patterns
Generator 1: Invert the color output.
Color Invert 0: Do not invert the color output.
Pattern
Generator
Auto-Scroll
Enable
Auto-Scroll Enable:
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.
0: The Pattern Generator retains the current pattern.
0x00 Indirect
Address
This 8-bit field sets the indirect address for accesses
to indirectly-mapped registers. It should be written prior
to reading or writing the Pattern Generator Indirect
Data register.
See AN-2198
0x00 Indirect
Data
When writing to indirect registers, this register contains
the data to be written. When reading from indirect
registers, this register contains the read back value.
