Used to upload sprite patterns. Sprite patterns are 16x16 (256 bytes) and are sent in English reading order. Each byte is the offset, 0-255, within the active sprite palette. After sending 256 bytes, the target sprite is auto-incremented. This auto-increment is independent of other sprite registers.
