1. (Condition after reset). Reload = FF, Port In = signal Out continuosly.
2. Reload = 03. At edge of Port In != Signal Out, Counter gets Reload Value and
3. Port In = Signal Out, counting stops.
4. At edge of Port In != Signal Out, Counter gets Reload Value and starts counting.
5. Counter underflows, stops, and Port In is driven to Signal Out.
6. At edge of Port In != Signal Out, counter gets Reload Value and starts counting.
7. Counter underflows, stops, and Port In is driven to Signal Out.
8. At edge of Port In != Signal Out, counter gets Reload Value and starts counting.
9. FF is written to Reload Value. Counter is stopped and loaded with FF.
