Field Name Bits Default Description SRC_ADDR 6:0 0x0 Specifies the location (within the shader pixel stack frame) of the texture address for this instruction SRC_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. SRC_S_SWIZ 9:8 0x0 Specify which colour channel of src_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 SRC_T_SWIZ 11:10 0x0 Specify which colour channel of src_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 SRC_R_SWIZ 13:12 0x0 Specify which colour channel of src_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 SRC_Q_SWIZ 15:14 0x0 Specify which colour channel of src_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 DST_ADDR 22:16 0x0 Specifies the location (within the shader pixel stack frame) of the returned texture data for this instruction DST_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 destination address 01 - RELATIVE: Add aL before lookup. DST_R_SWIZ 25:24 0x0 Specify which colour channel of the returned texture data to write to the red channel of dst_addr POSSIBLE VALUES: 00 - Write R channel to R channel 01 - Write G channel to R channel 02 - Write B channel to R channel 03 - Write A channel to R channel DST_G_SWIZ 27:26 0x0 Specify which colour channel of the returned texture data to write to the green channel of dst_addr POSSIBLE VALUES: 00 - Write R channel to G channel 01 - Write G channel to G channel 02 - Write B channel to G channel 03 - Write A channel to G channel DST_B_SWIZ 29:28 0x0 Specify which colour channel of the returned texture data to write to the blue channel of dst_addr POSSIBLE VALUES: 00 - Write R channel to B channel 01 - Write G channel to B channel 02 - Write B channel to B channel 03 - Write A channel to B channel DST_A_SWIZ 31:30 0x0 Specify which colour channel of the returned texture data to write to the alpha channel of dst_addr POSSIBLE VALUES: 00 - Write R channel to A channel 01 - Write G channel to A channel 02 - Write B channel to A channel 03 - Write A channel to A channel
