$(35$points$)$ Problem $4$

$1-(20$ pt$.)$ Design a Pentium III $16-$bit input and $16-$bit output port mapped to the same address $100$ F H $.$ Then interface eight common cathode LEDs and eight switches to the ports that you have designed.

$2-(15pt.)$ For the circuit you have designed, write the required assembly instructions to read the status of switches and turn ON or OFF the LEDs as the status of switches. $($ for example: if Switch $1$ is ON $$ LED$1$ is ON$,$ if Switch $1$ is OFF $$ LED$1$ is OFF$)$
