34 / 324 page ![]() 2.4 Addressing Modes 2.4.1 Addressing Modes The H8/300L CPU supports the eight addressing modes listed in table 2-1. Each instruction uses a subset of these addressing modes. Table 2-1 Addressing Modes No. Address Modes Symbol 1 Register direct Rn 2 Register indirect @Rn 3 Register indirect with displacement @(d:16, Rn) 4 Register indirect with post-increment @Rn+ Register indirect with pre-decrement @–Rn 5 Absolute address @aa:8 or @aa:16 6 Immediate #xx:8 or #xx:16 7 Program-counter relative @(d:8, PC) 8 Memory indirect @@aa:8 1. Register Direct—Rn: The register field of the instruction specifies an 8- or 16-bit general 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. 2. Register Indirect—@Rn: The register field of the instruction specifies a 16-bit general register containing the address of the operand. 3. Register Indirect with Displacement—@(d:16, Rn): The instruction has a second word (bytes 3 and 4) containing a displacement which is added to the contents of the specified general register to obtain the operand address. This mode is used only in MOV instructions. For the MOV.W instruction, the resulting address must be even. 23 |
