For each of the following instructions assume the initial register contents are: AX = 10C2H, BX = 5AB4H, CX = C176H, DX = 99A0H, and SI = 49ADH. Give the contents of each register that has data transferred to it by the instruction or sequence of instructions: mov cx, bx xchg dx, cx mov si, ax mov bx, ax mov ax, bx

Solution

contants of register BX 5AB4H=Z\'

note : register contents are converted from hexadecimal to ascii values .

2:XCHG REG, memory
memory, REG
REG, REG Exchange values of two operands. SO DX WILL HAVE THE VALUE OF CX ,

SO THE CONTENTS OF REGISTER :Av

3:

register contants =Â

4:mov bx,ax :

contants of register :Â

mov ax,bx:

contants of register :Z´
