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.
Because each command consists of two bytes of data, two consecutive I²C transmissions must be executed both
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.
