$1)(10$ pt$.)$ Design a circuit to build synchronous serial communication system between twoPIC$16$F$877$A microcontrollers as both of them acts as a transceiver. Show all connectionsin detail$\mathrm{.}2)(20$ pt$.)$ For the circuit you have designed, write a mikroC program to allow one of the PICmicrocontrollers to serially send the message of three characters "YES" to the second PICmicrocontroller that will then replies with the same message "YES". Note that twoprograms are required, one program for each PIC microcontroller
