DATA COMMANDS

STANDARD DATA COMMANDS

The bq27510-G3 fuel gauge uses a series of 2-byte standard commands to enable system reading and writing of

battery information. Each standard command has an associated command-code pair, as indicated in Table 1.

to initiate the command function, and to read or write the corresponding two bytes of data. Additional options for

transferring data are described in Section of COMMUNICATIONS. Standard commands are accessible in

NORMAL operation. Read and write permissions depend on the active access mode, SEALED or UNSEALED.

Additional details are found in the bq27510-G3 Technical Reference Manual.
