a$.$ Develop a time delay procedure for the $2\mathrm{.}0GHz$ Pentium$-$Core$2$ that waits for

$70ms$

b$.$ The $8255$ shown in the following is configured as follows: port A as output, B

as output, and port $C($low and high$)$ as input.

Find the port addresses assigned to $A,B,C$ and the control register

Find the control byte $($word$)$ for this configuration.

Program the ports to input data from port A and send it to both ports $B$ and

C$.$

Hint you can use delay in $($a$)$ if needed
