Hi there Without going into too much detail, does anyone know of any significant variations in the way that the timer0 module is implemented, across the 18F range? Or between 16F and 18F? (i.e. just in terms of functionality and register names). I'm hoping that timer0 is an identical internal peripheral throughout all PIC types.
