Implementation of a port test program for ATMEL AVR-Controller

@note An den Ports PORTA, PORTB, PORTC und PORTL werden Bitmuster ausgegeben.
Durch Verbindung der einzelnen Ports nacheinander mit
der Wannenstiftleiste SV8 (Px) am Print koennen die Bitmuster
entsprechend der Jumperstellung (JP1) visualisiert werden:
JP1 rechts:  7-Segmentanzeige
JP1 links:   LED-Balken
