a$)(10$ pt$.)$ Design a circuit to interface one push button and one common anode $7-$segment displayto PIC$16$F$84$A$.$ Show all connections in detail.b$)(20$ pt$.)$ For the circuit you have designed, and by initializing the Timer$0$ module as a counter,write a mikroC program by using timer$0$ Overflow interrupt technique to detect and count theaction on the pushbutton switch. The value of the count ranging from $0$ to $9$ is displayed on the$7-$segment display as $1$ increment for every $512$ presses on pushbutton. After reaching the valueof $9,$ the counter begins anew.
