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

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 $B$ and send it to both ports A and C$.$

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