May be modified by coprocessor; unchanged otherwise.
Coprocessor ID field—Identifies the coprocessor for this operation; note that
coprocessor. The coprocessor determines the specific operation from the command
word. Usually a coprocessor defines specific instances of this instruction to provide its
instruction set.
Effective Address field—Specifies the location of any operand not resident in the
Coprocessor Command field—Specifies the coprocessor operation to be performed.
