18.1.9 ManufacturerAccess() 0x0009 All DF Signature

The BQ40Z80 device can return the data flash checksum. The signature of all DF parameters returns on a subsequent read on ManufacturerBlockAccess() or ManufacturerData(). MSB is set to 1 if the calculated signature does not match the signature stored in DF. It is expected that this signature will change due to updates of lifetime, gauging, and other information.
