PRODUCTION DATA
If the application requires different configuration data for the fuel gauge, the system processor can update RAM-based data memory parameters using the Control() SET_CFGUPDATE subcommand to enter the CONFIG UPDATE mode. Operation in this mode is indicated by the Flags()[CFGUPMODE] status bit. In this mode, fuel gauging is suspended while the host uses the extended data commands to modify the configuration data blocks. To resume fuel gauging, the host must send a Control() SOFT_RESET subcommand to exit the CONFIG UPDATE mode which clears both Flags() [ITPOR] and [CFGUPMODE] bits. After a timeout of approximately 240 seconds (4 minutes), the gauge will automatically exit the CONFIG UPDATE mode if it has not received a SOFT_RESET subcommand from the host.
