Destination register

Destination register (abbr. ) is encoded in bits 2..0 of Register Operation (ROP) instructions.

The destination registers are specified as follows:

If no destination register is specified (value: 0) the instruction is normally transformed to a NOP (no-operation). EXIT, EXR, RDIV, MIX3 are exceptions to this and RADD clears the carry indicator (C) only.
