Instruction Set List (4/4)
Special
Instruction
Note The opcode of this instruction uses the field of reg1 even though the source register is shown as reg2 in the
Group
above table. Therefore, the meaning of the register specification for mnemonic description and opcode is
different from that of the other instructions.
