Gyroscope full-scale selection. Default value: 00
(00: 245 dps; 01: 500 dps; 10: Not Available; 11: 2000 dps)
Gyroscope bandwidth selection. Default value: 00
ODR_G [2:0] are used to set ODR selection when both the accelerometer and gyroscope
are activated. BW_G [1:0] are used to set gyroscope bandwidth selection.
The following table summarizes all frequencies available for each combination of the
ODR_G / BW_G bits after LPF1 (see Table 46) and LPF2 (see Table 47) when both the
accelerometer and gyroscope are activated. For more details regarding signal processing
please refer to Figure 28.
