Please note that when the part is operated in hybrid mode, the ODR is reduced by a factor of two, which also affects the filter
cutoff frequency. For example, an ODR setting of 400 Hz in accelerometer only mode with HP_FILTER_CUTOFF[sel] = 0b10
sets the cutoff frequency at 4 Hz. If the part is operated in Hybrid mode, the effective ODR becomes 200 Hz and the cutoff
frequency is now 2 Hz for the same ODR and HP_FILTER_CUTOFF[sel] settings.
