and notice the status of all registers besides the status of the flags

MOV AL$,55$

AND AL$,1F$

OR AL $,$ C$1$

NOT AL

Develop a short sequence of instruction that clear $(0)$ the three leftmost

bits of $DH$ without changing the reminder $DH$ and store the result in $BH$

$($assume that $DH=FF).$

Write a sequence of instruction that saves the contents of bit $5$ in $AL$ in

BX as word.

Implement the following operation using shift arithmetic instruction

$7(Ax)-5(Bx)-\frac{Bx}{8}$longrightarrowAx

Develop a sequence of instructions that set $(1)$ the leftmost four bits of

$Ax,$ clear $(0)$ the rightmost three bits of $Ax$ and invert bits $7,8$ and $9$ of

$Ax($ assume that $Ax=FFFF)$
