a$.$ Develop a time delay procedure for the $3\mathrm{.}0$ GHZ Pentium$-$Core$2$ that waits for $50$ms

b$.$ The $8255$ shown in the following is configured as follows: port A as input, B as output, 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 A and send it to both ports B and

$.$

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