A/D Example Main Routine
The main routine of demo877.asm (Figure 5.2) begins by configuring
PORTC, the A/D module and Timer0. It then waits for a Timer0 overflow to
start the A/D conversion of the value from the potentiometer. When the
conversion is complete, the value is displayed on the LEDs, and the program
loops back to wait for another Timer0 overflow to start another A/D
conversion.
