Description: DS18B20 memory includes a cache RAM and can be electrically erased RAM, which can be electrically erased RAM and temperature trigger TH and TL, as well as a configuration register. Memory can complete to determine the first port in communication, digital began to write register command written into the register, then can also register read command to confirm these numbers. When it is confirmed that it can be used after the copy register command to add these figures shifted to an electrically erasable RAM. When the modified register number, this process can ensure the integrity of digital.
High speed register RAM is composed of 8 bytes of memory the first and second bytes of the temperature of the display position. Third and fourth byte is the replication of TH and TL, while the third and fourth bytes of digital can update fifth bytes is to copy the configuration register, and fifth bytes of digital can update six or seven, eight three bytes of computer use. Use register read co
