Indicates the function of the instruction, and specifies the addressing mode and operation to be
carried out on the operand. The operation field always includes the first four bits of the
instruction. Some instructions have two operation fields.
Specifies a general register. Address registers are specified by 3 bits, data registers by 3 bits or
4 bits. Some instructions have two register fields. Some have no register field.
8, 16, or 32 bits specifying immediate data, an absolute address, or a displacement.
Specifies the branch condition of Bcc instructions.
(1) Operation field only
(2) Operation field and register fields
(3) Operation field, register fields, and effective address extension
