I'm not sure what the the code is addressing in each of these
addressing modes. I know that the opcode is moving data, but
where is the code addressing the code at in each addressing
modes:
register addressing
mov ax, bx
immediate
mov ax, 1
or
mov ax, 0x010C
direct memory addressing
mov ax, [102h]
direct offset addressing
byte_tab db 12, 15, 22
mov al, [byte_tab+2]
mov al, byte_tab[2]
register indirect
mov ax,[di]
base index
mov ax,[bx+di]
base index with displacement
mov ax, [bx + di + 10]
Jump to PostAll that code does is illustrate how to copy data into register ax from somewhere. For example:
mov ax,bxjust copies the value of bx into ax register. In another case,mov ax,[bx+di]it assumes the data is in the segment pointed to by the ds register. It could also …
All that code does is illustrate how to copy data into register ax from somewhere. For example: mov ax,bx just copies the value of bx into ax register. In another case, mov ax,[bx+di] it assumes the data is in the segment pointed to by the ds register. It could also have been written like this: mov ax,ds:[bx+di]
Yeah, It's just an illustration. I just want to know how each of the addressing modes work.
