2.4.1
The H8/300L CPU supports the eight addressing modes listed in table 2.1. Each instruction uses a
subset of these addressing modes.

1. Register Direct Rn: The register field of the instruction specifies an 8- or 16-bit general
2. Register Indirect @Rn: The register field of the instruction specifies a 16-bit general
3. Register Indirect with Displacement @(d:16, Rn): The instruction has a second word
4. Register Indirect with Post-Increment or Pre-Decrement @Rn+ or @–Rn:
register containing the operand.
Only the MOV.W, ADD.W, SUB.W, CMP.W, ADDS, SUBS, MULXU (8 bits 8 bits), and
DIVXU (16 bits ÷ 8 bits) instructions have 16-bit operands.
register containing the address of the operand in memory.
(bytes 3 and 4) containing a displacement which is added to the contents of the specified
general register to obtain the operand address in memory.
This mode is used only in MOV instructions. For the MOV.W instruction, the resulting
address must be even.
Register indirect with post-increment @Rn+
The @Rn+ mode is used with MOV instructions that load registers from memory.
The register field of the instruction specifies a 16-bit general register containing the address
of the operand. After the operand is accessed, the register is incremented by 1 for MOV.B
or 2 for MOV.W, and the result of the addition is stored in the register. For MOV.W, the
original contents of the 16-bit general register must be even.
