Description:
The ICM-20948 is specifically designed to coordinate the time between the ICM-20948 and external sensors.
An extra feature. In addition to using the module's dedicated interrupt INT pin, developers can use the external sensor's interrupt or sync pulse to drive the module's FSYNC pin to help developers simplify these multi-sensor designs. The ICM-20948 provides separate external sensors. 12C interface and built-in support. Developers here connect a 12C-compatible smart sensor to the module's dedicated auxiliary 12C port. While the SPI (or 12C) is connected to the host MCU, the developer can use the TDK tube to stream the InvenSense ICM-20948 module's auxiliary 12C interface (AUX_CL Connect external sensors to AUX_DA and manage them via the auxiliary device special registers of the lCM-20948.
