7.5 Programming
7.5.1 Standard Data Commands
The 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. 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 details are found in the bq27532-G1
Technical Reference Manual, SLUUB04.
