      Instruction

      Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. The figure below shows a block diagram of DS18B20. The scratchpad memory contains the 2-byte temperature register that stores the datal output from the temperature sensor. In addition, the scratchpad provides access to direct temperature alarm trigger registers (TH and TL) and the 1-byte configuration register. The configuration register allows the user to set the resolution of the temperature-to-digital conversion to 9, 10, 11, or 12 bits. The TH, TL, and configuration registers are nonvolatile (EEPROM), so they will retain data when the device is powered down.
