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

$70ms$

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

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

$1-$Find the port addresses assigned to $A,B,C$ and the control register

$2-$Find the control byte $($word$)$ for this configuration.

$3-$Program the ports to input data from port $B$ and send it to both ports A and

C$.$

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