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 coordinate POSSIBLE VALUES: 00 - Use R channel as S coordinate 01 - Use G channel as S coordinate 02 - Use B channel as S coordinate 03 - Use A channel as S coordinate DX_T_SWIZ 11:10 0x0 Specify which colour channel of dx_addr to use for T coordinate POSSIBLE VALUES: 00 - Use R channel as T coordinate 01 - Use G channel as T coordinate 02 - Use B channel as T coordinate 03 - Use A channel as T coordinate DX_R_SWIZ 13:12 0x0 Specify which colour channel of dx_addr to use for R coordinate POSSIBLE VALUES: 00 - Use R channel as R coordinate 01 - Use G channel as R coordinate 02 - Use B channel as R coordinate 03 - Use A channel as R coordinate DX_Q_SWIZ 15:14 0x0 Specify which colour channel of dx_addr to use for Q coordinate POSSIBLE VALUES: 00 - Use R channel as Q coordinate 01 - Use G channel as Q coordinate 02 - Use B channel as Q coordinate 03 - Use A channel as Q coordinate DY_ADDR 22:16 0x0 Specifies the location (within the shader pixel stack frame) of the DY value for this instruction DY_ADDR_REL 23 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. DY_S_SWIZ 25:24 0x0 Specify which colour channel of dy_addr to use for S coordinate POSSIBLE VALUES: 00 - Use R channel as S coordinate 01 - Use G channel as S coordinate 02 - Use B channel as S coordinate 03 - Use A channel as S coordinate DY_T_SWIZ 27:26 0x0 Specify which colour channel of dy_addr to use for T coordinate POSSIBLE VALUES: 00 - Use R channel as T coordinate 01 - Use G channel as T coordinate 02 - Use B channel as T coordinate 03 - Use A channel as T coordinate DY_R_SWIZ 29:28 0x0 Specify which colour channel of dy_addr to use for R coordinate POSSIBLE VALUES: 00 - Use R channel as R coordinate 01 - Use G channel as R coordinate 02 - Use B channel as R coordinate 03 - Use A channel as R coordinate DY_Q_SWIZ 31:30 0x0 Specify which colour channel of dy_addr to use for Q coordinate POSSIBLE VALUES: 00 - Use R channel as Q coordinate 01 - Use G channel as Q coordinate 02 - Use B channel as Q coordinate 03 - Use A channel as Q coordinate
