Problem $1$

Sketch the timing diagram for fetching and executing MOVSB instruction. $CS=1000H.DS=2000H,ES=3000H,IP=156H,SI=AB4DH$ and $DI=98$FEH

Instructions:

Draw a clear and labelled timing diagram representing the bus cycle of the $8088$ microprocessor. The sketch should show the following signals' respective values in each phase: Address bus, data bus, ALE, IO$/$M$,$ DEN. $RD,WR,S_3{S}_4{S}_5{S}_6$

Highlight the fetch and execute phases of the cycle. Show the values of
