The Gsensor can be connected to the main MCU or the sensor Hub MAX32664, but the following points should be noted,
1. The Gsensor is connected to the main MCU and can read the data directly when it is used for step counting and other applications, so the MAX32664 does not need to transfer the data, so it saves more power.
2. Gsensor is connected to the Sensor Hub MAX32664. For HR and Spo2, Gsensor and BIO Sensor have better synchronization, which is more conducive to algorithm processing.
