What value will be in the AL register after the following instruction is executed? MOV BL,05 MOV AL,02 MOV BL, AL The following instruction will give an error. Explain why. MOV BX,[AX] Explain the purpose or use of the w bit in op codes. Write the hexadecimal code for each of these instructions using the information attached. Show your work. MOV CL,DL MOV DX,4567 MOV [4567], cx mov cx, [bx + DI + 4567] mov [bp + si + 20], dx

Solution

(8) After the first instruction, BL=05

After the second instruction, AL=02

After the last instruction, BL=AL=02

So finally, after given instruction set is executed

AL=02
