Question $7$:

a$)$ Suppose that $DS=2000H,SS=3000H,SP=3F7FH,BP=3000H,Bx=0500H,DI=0300H,$ LIST $=0270H.$ Determine the physical memory address accessed by each of the following instructions and explain the operation of each instruction, assuming real mode operation:

i$)$ MOV AL$,BP+DI$

iii$)$ MOV AL$,1234H$

ii$)$ MOV LIST$[$BX$+$DI$+4],$ DL

iv$)$ POP CX

b$)$ Using the addressing modes that you have studied, Write an assembly program to record $40$ values for the clock of your computer system. $($Assuming the time of the clock needs $2$ bytes and is saved at address $046$ CH in the Extra segment$)$

c$)$ Explain, with the aid of drawings, the PUSH and POP stack instructions. Assuming the values given in question $7($a$).$
