$(8$ pts$)$ Write a short $($but complete and legal$)$ AVR C program to continuously monitor

PORTC pin $3.$ Based on the value of PORTC$\mathrm{.}3,$ write values to the upper nibble of PORTD

and PORTE as follows:

All pins of PORTC should be set as inputs, and all pins of PORTD and PORTE should be

set as outputs. Note that in all cases the lower nibbles of PORTD and PORTE must not be

modified $($i$.$e$.$ whatever value they currently have must be maintained as you change the

upper four bits$).$

It is good $($but not required$)$ to use C programming logical operators and port pin

declarations, e$.$g$.$ PORTA PA$1$
