Register Direct—Rn
The register field of the instruction code specifies an 8-, 16-, or 32-bit general register containing
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.
Register Indirect—@ERn
The register field of the instruction code specifies an address register (ERn) which contains the
address of the operand in memory. 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).
Register Indirect with Displacement—@(d:16, ERn) or @(d:32, ERn)
A 16-bit or 32-bit displacement contained in the instruction 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.
