• Description: 16-bit Single-chip Microcomputer H8s Family / H8s/2400 Series
• Manufacturer: Renesas Electronics Corporation.

2.7
The H8S/2600 CPU supports the eight addressing modes listed in table 2.11. The usable address
modes are different in each instruction.
Arithmetic and logic instructions can use the register direct and immediate modes. Data transfer
instructions can use all addressing modes except program-counter relative and memory indirect.
Bit manipulation instructions use register direct, register indirect, or absolute addressing mode to
specify an operand, and register direct (BSET, BCLR, BNOT, and BTST instructions) or
immediate (3-bit) addressing mode to specify a bit number in the operand.
Addressing Modes and Effective Address Calculation
(1) Operation field only
(2) Operation field and register fields
(3) Operation field, register fields, and effective address extension
(4) Operation field, effective address extension, and condition field
