FUNCTION
Writes 64-bit challenge for SHA-1 processing. Required prior to all Compute
MAC and Compute Next Secret commands.
Computes hash of W0-W15 with logical 1’s in place of the ROM_ID.
Computes hash of W0-W15 with the ROM_ID.
Writes the 64-bit Secret to supplied data. Requires programming voltage on
DQ.
Generates new global secret. Requires programming pulse.
Generates new unique secret. Requires programming pulse.
Sets lock bit to prevent changes to the Secret. Requires programming pulse.
Sets 1-Wire interface timings to OVERDRIVE. Requires programming pulse.
Sets 1-Wire interface timings to STANDARD. Requires programming pulse.
Activates the THM output for thermistor measurement. Activation occurs within
50μs of command completion and continues until the VB capacitor is
discharged.
Resets DS2703 (Software POR).
