DS1920

Read Scratchpad [BEh]
This command reads the complete scratchpad. After the last byte of the scratchpad is read, the bus master
will receive an 8-bit CRC of all scratchpad bytes. If not all locations are to be read, the master may issue
a reset to terminate reading at any time.
Copy Scratchpad [48h]
This command copies from the scratchpad into the EEPROM of the DS1920, storing the temperature
trigger bytes in nonvolatile memory. The bus master has to enable a strong pullup for at least 10 ms
immediately after issuing this command.
Convert Temperature [44h]
This command begins a temperature conversion. No further data is required. The bus master has to enable
a strong pullup for 0.5 seconds immediately after issuing this command.
Recall [B8h]
This command recalls the temperature trigger values stored in EEPROM to the scratchpad. This recall
operation happens automatically upon power-up to the DS1920 as well, so valid data is available in the
scratchpad as soon as the device has power applied.
