Define variables to be used in main program.

Define pin names to be used in the main program. Both are defined as 8-bit numbers, with count already being assigned a value while temp is left unassigned. Retrieved from ” http: Ideally it should also be volatile as it’s used in both main and interrupt. Working with digital inputs and outputs is fundamental to circuit design, and PIC microcontrollers add versatility to design by allowing programming and re-programming of the logic associated with input and output pins.

This is a more explicit way of saying main is a function of nothing.
