Read ROM [33h] This command can only be used when there is one slave on the bus. It allows the bus master to read the slave’s 64-bit ROM code without using the Search ROM procedure. If this command is used when there is more than one slave present on the bus, a data collision will occur when all the slaves attempt to respond at the same time.............

Yes i am using search algorithm, but i do not know affter search how to extract addresses i am not sure if they ar save in some viaribale.
