Description
GX_BASE+810Ch-810Dh
GP_SRC_COLOR_0 Register (R/W)
Default Value = 0000h
15:0 8-bpp Mode: 8-bpp color: The color index must be duplicated in the upper byte.
16-bpp Mode: 16-bpp color (RGB)
GX_BASE+810Eh-810Fh
GP_SRC_COLOR_1 Register (R/W)
Default Value = 0000h
15:0
Note:
8-bpp Mode: 8-bpp color: The color index must be duplicated in the upper byte.
16-bpp Mode: 16-bpp color (RGB)
The Graphics Pipeline Source Color register specifies the colors used when expanding monochrome source data in either
the 8-bpp mode or the 16-bpp mode. Those pixels corresponding to clear bits (0) in the source data are rendered using
GP_SRC_COLOR_0 and those pixels corresponding to set bits (1) in the source data are rendered using
GP_SRC_COLOR_1.
GX_BASE+8110h-8111h
GP_PAT_COLOR_0 Register (R/W)
Default Value = 0000h
15:0
Note:
8-bpp Mode: 8-bpp color: The color index must be duplicated in the upper byte.
16-bpp Mode: 16-bpp color (RGB)
The Graphics Pipeline Pattern Color 0-3 registers specify the colors used when expanding pattern data.
GX_BASE+8112h-8113h
GP_PAT_COLOR_1 Register (R/W)
Default Value = 0000h
15:0
Note:
8-bpp Mode: 8-bpp color: The color index must be duplicated in the upper byte.
16-bpp Mode: 16-bpp color (RGB)
The Graphics Pipeline Pattern Color 0-3 registers specify the colors used when expanding pattern data.
GX_BASE+8114h-8115h
GP_PAT_COLOR_2 Register (R/W)
Default Value = 0000h
15:0
8-bpp Mode: 8-bpp color: The color index must be duplicated in the upper byte.
16-bpp Mode: 16-bpp color (RGB)
Note: The Graphics Pipeline Pattern Color 0-3 registers specify the colors used when expanding pattern data.
GX_BASE+8116h-8117h
GP_PAT_COLOR_3 Register (R/W)
Default Value = 0000h
15:0
8-bpp Mode: 8-bpp color: The color index must be duplicated in the upper byte.
16-bpp Mode: 16-bpp color (RGB)
Note: The Graphics Pipeline Pattern Color 0-3 registers specify the colors used when expanding pattern data.
GX_BASE+8120h-8123h
GP_PAT_DATA_0 Register (R/W)
Default Value = 00000000h
31:0 GP Pattern Data Register 0: The Graphics Pipeline Pattern Data registers 0 through 3 together contain 128 bits of pat-
tern data. The GP_PAT_DATA_0 register corresponds to bits [31:0] of the pattern data.
GX_BASE+8124h-8127h
GP_PAT_DATA_1 Register (R/W)
Default Value = 00000000h
31:0 GP Pattern Data Register 1: The Graphics Pipeline Pattern Data registers 0 through 3 together contain 128 bits of pat-
tern data. The GP_PAT_DATA_1 register corresponds to bits [63:32] of the pattern data.
GX_BASE+8128h-812Bh
GP_PAT_DATA_2 Register (R/W)
Default Value = 00000000h
31:0 GP Pattern Data Register 2: The Graphics Pipeline Pattern Data registers 0 through 3 together contain 128 bits of pat-
tern data. The GP_PAT_DATA_2 register corresponds to bits [95:64] of the pattern data.
GX_BASE+812Ch-812Fh
GP_PAT_DATA_3 Register (R/W)
Default Value = 00000000h
31:0 GP Pattern Data Register 3: The Graphics Pipeline Pattern Data registers 0 through 3 together contain 128 bits of pat-
tern data. The GP_PAT_DATA_3 register corresponds to bits [127:96] of the pattern data.
GX_BASE+8140h-8143h
GP_VGA_WRITE Register (R/W)
Default Value = xxxxxxxxh
Note that the register at GX_BASE+82140h is located in the area designated for the graphics pipeline but is used for VGA emulation
purposes. Refer to Table 4-39 on page 166 for this register’s bit formats.
