... The first 32 bytes of the DS2502-E64’s EPROM memory contain a globally unique 64-bit node address (EUI-64) and are write-protected. The data structure follows the conventions of UniqueWare devices using Default Data Structure (Figure 1). This format is also known as UDP (universal data packet) and is commonly used in 1-Wire APIs. Therefore, if using one of those APIs one can call a high level function to read and verify the inverted CRC16 ...
