4. Register Indirect with Post-Increment or Pre-Decrement—@ERn+ or @–ERn
5. Absolute Address—@aa:8, @aa:16, or @aa:24
The instruction code contains the absolute address of a memory operand. The absolute address
may be 8 bits long (@aa:8), 16 bits long (@aa:16), or 24 bits long (@aa:24). For an 8-bit absolute
address, the upper 16 bits are all assumed to be 1 (H'FFFF). For a 16-bit absolute address the
upper 8 bits are a sign extension. A 24-bit absolute address can access the entire address space.
Table 2.12 indicates the accessible address ranges.

Register indirect with post-increment—@ERn+
The register field of the instruction code specifies an address register (ERn) the lower 24 bits
of which contain the address of a memory operand. After the operand is accessed, 1, 2, or 4 is
added to the address register contents (32 bits) and the sum is stored in the address register.
The value added is 1 for byte access, 2 for word access, or 4 for longword access. For word or
longword access, the register value should be even.
Register indirect with pre-decrement—@–ERn
The value 1, 2, or 4 is subtracted from an address register (ERn) specified by the register field
in the instruction code, and the lower 24 bits of the result become the address of a memory
operand. The result is also stored in the address register. The value subtracted is 1 for byte
access, 2 for word access, or 4 for longword access. For word or longword access, the resulting
register value should be even.
