2.7.1
The register field of the instruction code specifies an 8-, 16-, or 32-bit general register which
contains the operand. R0H to R7H and R0L to R7L can be specified as 8-bit registers. R0 to R7
and E0 to E7 can be specified as 16-bit registers. ER0 to ER7 can be specified as 32-bit registers.
2.7.2
The register field of the instruction code specifies an address register (ERn) which contains the
address of a memory operand. If the address is a program instruction address, the lower 24 bits are
valid and the upper 8 bits are all assumed to be 0 (H'00).
2.7.3
A 16-bit or 32-bit displacement contained in the instruction code is added to an address register
(ERn) specified by the register field of the instruction, and the sum gives the address of a memory
operand. A 16-bit displacement is sign-extended when added.
2.7.4
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, and 4 for longword
access. For word or longword transfer instructions, the register value should be even.
