Graphics Processor Register Definitions
6.4.2.10 Pattern Data (GP_PAT_DATA_x)
GP Memory Offset 30h
Type
Reset Value
In solid pattern mode, these registers are not used.
In monochrome pattern mode, GP_PAT_DATA_0 and GP_PAT_DATA_1 combine to hold the entire 8x8 pattern (64 bits).
GP_PAT_DATA_0[7:0] is the first line of the pattern, with bit 7 corresponding to the leftmost pixel on the screen.
GP_PAT_DATA_1[31:24] is the last line of the pattern.
In color pattern mode, these registers each hold part of the pattern according to Table 6-31.
6.4.2.11 Raster Mode (GP_RASTER_MODE)
GP Memory Offset 38h
Type
Reset Value
This register controls the manipulation of the pixel data through the graphics pipeline. Refer to section Section 6.3.10 "Ras-
ter Operations (ROP)" on page 249 for more information on the functionality of the ROP and Section 6.3.11 "Image Com-
positing Using Alpha" on page 250 for information on alpha blending and compositing. This register is byte writable to allow
modification of the ROP and other control bits without having to rewrite the BPP and FMT every time.
