Section 2 CPU
longword transfer instruction. For the word or longword transfer instructions, 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 is 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 transfer instruction, or 4 for longword transfer
instruction. For the word or longword transfer instructions, the register value should be even.
2.7.5
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). Table 2.12 indicates the accessible absolute address ranges.
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'FFFF).
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).

Note:
2.7.6
The instruction contains 8-bit (#xx:8), 16-bit (#xx:16), or 32-bit (#xx:32) immediate data as an
operand.
