Explain what happens when the following sequence of instructions is executed.

LAFH

MOV $[$BX$+$DI$],$ AH

What operation is performed by the instruction sequence that follows?

MOV AH$,[$BX$+$SI$]$

SAHF

Write an instruction sequence to configure the $8088$ as follows: save the original contents of flags SF$,$ ZF$,$ AF$,$ PF$,$ and CF at the address $0AO{000}_{16}$; and then clear CF$.$

Describe the operation performed by each of the instructions that follow.

a$)$ CMP $[0100H],AL$

b$)$ CMP AX$,[$SI$]$

c$)$ CMP WORD PTR $[$DI$],1234H$

What happens to the $ZF$ and $CF$ status flags as the following sequence of instructions is executed? Assume that both are initially cleared.Assume CS $=1075$H$,$IP$=0300$H$,$SI$=0100$H$,$DS:$0100=00$H$,$ and DS:$0101=10$H and show the operation when the following sequence of instructions is executed.JMP $10$HJMP $100$HJMP WORD PTR $[$SI$]$Assuming the same values provided in problem $6,$ show the operation performed when the following sequence of instructions is executed.JNC $10$HJNP $1000$HJO WORD PTR $[$SI$]$
