1.6.4
The H8S/2600 or H8S/2000 instructions consist of 2-byte (1-word) units. An instruction consists
of an operation field (op field), a register field (r field), an effective address extension (EA field),
and a condition field (cc).
Operation Field: Indicates the function of the instruction, the addressing mode, and the 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.
Register Field: 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.
Effective Address Extension: Eight, 16, or 32 bits specifying immediate data, an absolute
address, or a displacement.
Condition Field: Specifies the branching condition of Bcc instructions.
Figure 1.12 shows examples of instruction formats.
