... ROM data. Match ROM [55h] / Skip ROM [CCh] The complete 1-Wire protocol for all Dallas Semiconductor iButtons contains a Match ROM and a Skip ROM command. (See the Book of DS19xx iButton Standards). Since the DS2401 contains only the 64-bit ROM with no additional data fields, the Match ROM and Skip ROM are not applicable and will cause no further activity on the 1-Wire bus if executed ...
