Write an assembly program to perform the following:

If $sw1(PDO)=A$

If $sw2(PD1)=A$

If $sw3(PD2)=A$

If $sw4(PD3)=A,===>$ The output of $($PORTB$)$ equal $(A^{\text{'}}{A}^{\text{'}}{A}^{\text{'}}{A}^{\text{'}}A$ A A A$)$

If $sw5(PD4)=A$

If $sw6(PD5)=A$

If $sw7(PD6)=A$

If sw$8($PD$7)=A$

Where: A equals $0$ or

$1.$
