It is not yet fully understood how registers are organized. It does however seem that registers are separated into various banks, some RO, some WO and some RW. Because of this separation, a given register ID may not refer to the same register value when it is used as SRC or as DST.

Attribute (input, RO) registers are located within the 0x0-0x10 range. What data they are fed is specified by the CPU.

Registers within the 0x20-0x40 ranges seem to be RW. They contain uniforms, such as matrix data.
