Cell information is stored in the fuel gauge in non-volatile flash memory. Many of these data flash locations are accessible during application development. They cannot, generally, be accessed directly during end-equipment operation. Access to these locations is achieved by either use of the companion evaluation software, through individual commands, or through a sequence of data-flash-access commands. To access a desired data flash location, the correct data flash subclass and offset must be known.
The fuel gauge provides 64 bytes of user-programmable data flash memory, partitioned into two 32-byte blocks: Manufacturer Info Block A and Manufacturer Info Block B. This data space is accessed through a data flash interface.
