/**
 * @brief Extended sensor attributes for ICM42670 6-axis MEMS sensor
 *
 * This exposes attributes for the ICM42670 which can be used for
 * setting the signal path filtering parameters.
 *
 * The signal path starts with ADCs for the gyroscope and accelerometer.
 * Low-Noise Mode and Low-Power Mode options are available for the
 * accelerometer. Only Low-Noise Mode is available for gyroscope.
 * In Low-Noise Mode, the ADC output is sent through an Anti-Alias Filter
 * (AAF). The AAF is a filter with fixed coefficients (not user configurable),
 * also the AAF cannot be bypassed. The AAF is followed by a 1st Order Low Pass
 * Filter (LPF) with user selectable filter bandwidth options.
 * In Low-Power Mode, the accelerometer ADC output is sent through an Average
 * filter, with user configurable average filter setting.
 * The output of 1st Order LPF in Low-Noise Mode, or Average filter in Low-Power
 * Mode is subject to ODR selection, with user selectable ODR.
