- If PORTxn is written logic one when the pin is configured as an input pin, the pull-up resistor is activated.
pinMode(PB0,INPUT); // set PB0 as input digitalWrite(PB0,HIGH); // enable the internal pull-up resistor
- If PORTxn is written logic one when the pin is configured as an output pin, the port pin is driven high (one).
