SLUUB65B May 2015 – December 2022
Instructs the fuel gauge to calculate chemistry checksum as a 16-bit unsigned integer sum of all static chemistry data. The most significant bit (MSB) of the checksum is masked yielding a 15-bit checksum. This checksum is compared with value stored in the data flash Static Chem DF Checksum. If the value matches, the MSB is cleared to indicate pass. If it does not match, the MSB is set to indicate failure. The checksum can verify the integrity of the chemistry data stored internally.
The Static Chem DF Checksum is programmed by the Chemistry programming tool.
