Pattern Generator Block
The integrated Pattern Generator displays a set of graphic patterns to help debugging systems and
test LCD panels. It is located ahead of the color management block, all generated colors are subject
to further transforms.
The screen can be split into a programmable grid of up to 8x8 areas. One of two independent
programmable patterns are displayed in each area.
Screen Split
A set of eight Grid registers grid0 - grid7, each with 8 bits, represents a block map of the grid (8x8
blocks). Each bit from the Grid registers represents one rectangular (gridX)x(gridY) block of pixels
which covers the LCD screen display area. Within these registers, a 0 selects Pattern 0 (defined
below) and a 1 selects Pattern 1.
All cells are the same size, defined by one horizontal and one vertical grid block size registers gridX
and gridY .
