9 Gauge Communication

This section introduces host-processor communication with the BQ27Z746. The BQ27Z746 gauge uses an I2C communication interface with communication speeds up to 400kHz. Further hardware and software specifications for the I2C interface for this gauge can be found in the device-specific data sheet and the BQ27Z746 Technical Reference Manual.
