I'm using a SPI interface to access the ICM-20948. I've been unable to communicate with the magnetometer via auxiliary I2C master mode and have a couple of simple questions.
1- Are the transactions with the magnetometer visible on the package AUX_CL and AUX_DA pins?
2- Do the AUX_CL and AUX_DA pins need external pullup resistors even when using the internal magnetometer?
