It is a common technique to read or write subsequent registers with a single instruction. For example TEXS (used to sample a texture) reads the texture coordinates from Ra and Ra+1, although it gets more complex with other layouts like 3D textures (it's not Ra+2). The result of the sample is given in an Rd and their subsequent registers. | It is a common technique to read or write subsequent registers with a single instruction.
