2.7
2.7.1
The CPU supports the eight addressing modes listed in table 2.4. Each instruction uses a subset of
these addressing modes. Arithmetic and logic instructions can use the register direct and
immediate modes. Data transfer instructions can use all addressing modes except program-counter
relative and memory indirect. Bit-manipulation instructions use register direct, register indirect, or
absolute addressing mode to specify an operand, and register direct (BSET, BCLR, BNOT, and
BTST instructions) or immediate (3-bit) addressing mode to specify a bit number in the operand.
Table 2.4
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.
No.
