... The first 32 bytes of the DS2502-E48’s EPROM memory contain a globally unique 48-bit node address 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 ...

... CRC values including examples in both hardware and software, see Application Note 27, Understanding and Using Cyclic Redundancy Checks with Maxim iButton The contents of the memory address range 0Dh to 1Fh is FFh. These cells cannot be altered since the whole memory page is write-protected. The memory range from 20h to 7Fh, however, is user- programmable ...
