Revision 3.1

Integrated Functions (Continued)

Note: 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-8113h

GP_PAT_COLOR_A Register (R/W)

Default Value = 00000000h

8-BPP Mode

31:24

GP_PAT_COLOR_0:

8-BPP Color Index — The color index must be duplicated in the upper byte of GP_PAT_COLOR_0 when rendering 8-BPP

data.

23:16

15:8

GP_PAT_COLOR_1:

8-BPP Color Index — The color index must be duplicated in the upper byte of GP_PAT_COLOR_1 when rendering 8-BPP

data.

7:0

16-BPP Mode

31:16

GP_PAT_COLOR_0: 16-BPP Color (RGB)

15:0

GP_PAT_COLOR_1: 16-BPP Color (RGB)

Note: The Graphics Pipeline Pattern Color A and B Registers specify the colors used when expanding pattern data.

GX_BASE+8114h-8117h

GP_PAT_COLOR_B Register (R/W)

Default Value = 00000000h

8-BPP Mode

31:24

GP_PAT_COLOR_2:

8-BPP Color Index — The color index must be duplicated in the upper byte of GP_PAT_COLOR_2 when rendering 8-BPP

data.

23:16

15:8

GP_PAT_COLOR_3:

8-BPP Color Index — The color index must be duplicated in the upper byte of GP_PAT_COLOR_3 when rendering 8-BPP

data.

7:0

16-BPP Mode

31:16

GP_PAT_COLOR_2: 16-BPP Color (RGB)

15:0

GP_PAT_COLOR_3: 16-BPP Color (RGB)

Note: The Graphics Pipeline Pattern Color A and B 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 registers at GX_BASE+82140h and 8144h are located in the area designated for the graphics pipeline but are used for

VGA emulation purposes. Refer to Table 5-5 on page 173 for these register’s bit formats.

GX_BASE+8144h-8147h

GP_VGA_READ Register (R/W)

Default Value = 00000000h

Note that the registers at GX_BASE+82140h and 8144h are located in the area designated for the graphics pipeline but are used for

VGA emulation purposes. Refer to Table 5-5 on page 173 for these register’s bit formats.
