4. Register Indirect with Post-Increment or Pre-Decrement—@ERn+ or @–ERn:
5. Absolute Address—@aa:8, @aa:16, @aa:24, or @aa:32: 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), 24 bits long (@aa:24), or 32 bits long (@aa:32).
To access data, the absolute address should be 8 bits (@aa:8), 16 bits (@aa:16), or 32 bits
(@aa:32) long. For an 8-bit absolute address, the upper 24 bits are all assumed to be 1
(H'FFFFFF). For a 16-bit absolute address the upper 16 bits are a sign extension. A 32-bit absolute
address can access the entire address space.
A 24-bit absolute address (@aa:24) indicates the address of a program instruction. The upper 8
bits are all assumed to be 0 (H'00).
Table 1.5 indicates the accessible absolute address ranges.

Register indirect with post-increment—@ERn+
The register field of the instruction code specifies an address register (ERn) which contains the
address of a memory operand. After the operand is accessed, 1, 2, or 4 is added to the address
register contents 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 result becomes 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 register value should be even.
Absolute Address Access Ranges
