Piclisters! My next question deals with unused PIC I/O pins. Should they be made either an input or output (software), left floating or tied to gnd or +5v? I am unfortunately using a 28 pin 16c63 dedicated to oscillating a single pin via hardware USART. Quick additional other question: Are there any other PICs available that have hardware USART?
