Uniquely identify a PCB through an external ROM

Dear all,

     I need to uniquely identify a PCB that uses ADUCM3029 as micro-controller. For that i'm connecting a ROM using 1-wire protocol in a GPIO pin. I browsed the ADI drivers and examples however I didn't find anything related to this matter, so I started writing a 1-wire protocol driver to read this ROM. One of the configuration needed is a pull-up resistor connecting to this pin. I'm asking:

what is value of the internal GPIO pull-up resistors?

Did Analog Devices has already an example or documentation concerning the 1-wire protocol?
