Default DS18B20 temp sensor IC

DS18B20 temp sensor IC Dq pin is connected to PSEN of controller in my application.
But in datasheet its mentioned that its connected to I/O port.
And second doubt is how I/O port senses temp? It should be connected to ADC pin of controller.Here is the datesheet of ds18b20.
