Table 220 shows cutoff and phase values obtained with all configurations
Enables gyroscope's OIS chain HPF. This filter is available on the OIS chain
only if HP_EN_G in CTRL7_G (16h) is set to '0'⁽¹⁾.
1. HP_EN_OIS is active to select HPF on the auxiliary SPI chain only if HPF is not already used in the
primary interface.

Sampling data with frequency equal or higher to 3.3 kHz is recommended.
If data is down-sampled @ 1 kHz, it is recommended to use a cutoff @ 173 Hz.
If data is down-sampled @ 2 kHz, it is recommended to use a cutoff @ 237 Hz.
