SLUUB65B May 2015 – December 2022
Instructs the fuel gauge to calculate data flash checksum as a 16-bit unsigned integer sum of all data flash excluding device-specific variables. The most significant bit (MSB) of the checksum is masked yielding a 15-bit checksum. This checksum is compared with the value stored in the data flash ALL 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 data flash stored internally.
