- // port A as input and switching Pull-up resistors on
- // DDRA=0x00
- // PORTA=0xFF
- // port C as output and initial value FF
- // DDRB=0xFF
- // PORTA=0xFF
- //
- // Writing a logic one to PINxn toggles the value of PORTxn, independent on the value of DDRxn
- // Note that the SBI instruction can be used to toggle one single bit in a port.
- // 2. Enable interrupts if needed
- // sei();
- // 3. Place here main code
