ICM-20948 Circuit

The ICM-20948 is an I²C master to the optional external sensor. The ICM-20948 has limited capabilities as an I²C Master and depends on the system processor to manage the initial configuration of any auxiliary sensors. The ICM-20948 has an interface bypass multiplexer, which connects the system processor I²C bus pins 23 and 24 (SCL and SDA) directly to the auxiliary sensor I²C bus pins 7 and 21 (AUX_CL and AUX_DA). 

Once the auxiliary sensors have been configured by the system processor, the interface bypass multiplexer should be disabled so that the ICM-20948 auxiliary I²C master can take control of the sensor I²C bus and gather data from the auxiliary sensors.
