3.7.2 Data address
The data address is an address for reading/writing the operand data of each instruction. Normally, an address is a
concept used for memory or I/O, but this operand address includes data in registers, immediate data and I/O data.
(1) Non-memory addressing
Non-memory addressing specifies data in registers, immediate data and I/O data.
(a)
Register addressing
Specifies the register from/to which the register specification field in an operation code reads/writes the
operand data.
The register addressing is shown in the following description.
General Description
Register that can be Described
reg, reg'
AW, BW, CW, DW, SP, BP, IX, IY, AL, AH, BL, BH, CL, CH, DL, DH
reg8, reg8'
AL, AH, BL, BH, CL, CH, DL, DH
reg16, reg16'
AW, BW, CW, DW, SP, BP, IX, IY
sreg
PS, SS, DS0, DS1
acc
AW, AL
Example of usage:
reg16 : MOV AW, IX
reg8
: ADD AL, CH
; AW
←
IX
; AL
←
AL + CH
(b)
Immediate addressing
1-byte or 2-byte data in an operation code becomes read-only operand data. Immediate addressing cannot
be used for the destination operand of an instruction.
Immediate addressing is shown in the following description.
General Description
Value that can be Described
imm8
0 to FFH (0 to 255 or
128 to +127)
0 to FFFFH (0 to 65535 or
32768 to +32767)
0 to FFFFH (0 to 65535 or
32768 to +32767)
0 to FFFFH (0 to 65535) … normally even
imm16
imm
pop_value
Example of usage:
imm16
imm8
pop_value : RET 16
: MOV AW, 216 ; AW
←
216
: SHL AL, 5
; Shifts AL to left by 5 bits.
; Deletes unnecessary 16 bytes on stack.
(c)
I/O addressing
I/O addressing specifies data in a 64-K byte I/O space.
There are two kinds of specification method in I/O addressing as shown below, and these are used by an
input/ output instruction.
