Sensor ODR can be selected according to the specific application (up to 6.6 kHz). However, MLC is limited to four available data rates in ASM330LHHX: 12.5 Hz, 26 Hz, 52 Hz, 104 Hz. The data rate for MLC inputs is set through the MLC_ODR bits. If the sensor ODR is higher than MLC_ODR, MLC automatically decimates the input data (without any additional filtering).
It is recommended to select MLC_ODR equal to the sensor ODR to avoid decimation of the MLC inputs.
Selecting MLC_ODR lower than the sensor ODR is also possible, but the different frequency response could lower the accuracy of the MLC solution.
