Field Name Bits Default Description
|
|
DX_ADDR 6:0 0x0 Specifies the location (within the shader pixel stack
|
|
frame) of the DX value for this instruction
|
|
DX_ADDR_REL 7 0x0 Specifies whether the loop register is added to the value
|
|
of the associated address before it is used. This
|
|
implements relative addressing.
|
|
POSSIBLE VALUES:
|
|
00 - NONE: Do not modify source address
|
|
01 - RELATIVE: Add aL before lookup.
|
|
DX_S_SWIZ 9:8 0x0 Specify which colour channel of dx_addr to use for S
|
|

|
|
POSSIBLE VALUES:
|
|
00 - Use R channel as S coordinate
|
|
01 - Use G channel as S coordinate
|
|
02 - Use B channel as S coordinate

|
|
of the associated address before it is used. This
|
|
implements relative addressing.
