2.6.2
The H8S/2000 CPU instructions consist of 2-byte (1-word) units. An instruction consists of an
operation field (op), a register field (r), an effective address extension (EA), and a condition field
(cc).
Figure 2.11 shows examples of instruction formats.
• Operation Field
• Register Field
• Effective Address Extension
• Condition 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.
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 branching condition of Bcc instructions.
Basic Instruction Formats
