To learn how to use MPLAB Integrated Development Environment (IDE) for code generation, simulation, and debugging. This code is a very simple program that sets up PORTC and PORTB I/Os and sends some values over these ports, and tries to read Port C and increments a counter and resets to a predetermined value when the counter rolls over to zero. All labels start in the first column, and the last line has an end directive. For detailed information, refer to the PIC18F452 datasheet on the course web page.
