Function Description
101 0x65 Pattern
Generator
Configuration 7 0x00
Reserved
6 RW Checkerb
oard Scale Scale Checkered Patterns:
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
Checkerb
oard Use Custom Checkerboard Color
0: Use white and black in the Checkerboard
pattern (default)
1: Use the Custom Color and black in the
Checkerboard pattern
4 RW 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.
3 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.
See TI App Note AN-2198.
1 RW Color
Invert Enable Inverted Color Patterns:
0: Do not invert the color output. (default)
1: Invert the color output.
See TI App Note AN-2198.
0 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.
See TI App Note AN-2198.

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.
