97 / 116 page  DocID030686 Rev 2 97/116 ISM330DLC Register description 116 DEN mode selection can be done using the LVL1_OIS bit of register CTRL1_OIS (70h) and the LVL2_OIS bit of register INT_OIS (6Fh). DEN mode on the OIS path is active in the gyroscope only. 10.88 CTRL2_OIS (71h) OIS configuration register. Primary interface for read-only (r); only Aux SPI can write to this register (r/w). 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. Table 213. DEN mode selection LVL1_OIS, LVL2_OIS DEN mode 10 Level-sensitive trigger mode is selected 11 Level-sensitive latched mode is selected Table 214. CTRL2_OIS register 0(1) 1. This bit must be set to '0' for the correct operation of the device. 0(1) HPM1_ OIS HPM0_ OIS 0(1) FTYPE_1_ OIS FTYPE_0_ OIS HP_EN_ OIS Table 215. CTRL2_OIS register description HPM[1:0]_OIS Gyroscope's OIS chain digital high-pass filter cutoff selection. Default value: 00 (00: 16 mHz; 01: 65 mHz; 10: 260 mHz; 11: 1.04 Hz) FTYPE_[1:0]_OIS Gyroscope's digital LPF1 filter bandwidth selection Table 216 shows cutoff and phase values obtained with all configurations HP_EN_OIS 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. Table 216. Gyroscope OIS chain LPF1 bandwidth selection FTYPE_[1:0]_OIS ODR = 6.6 kHz BW Phase delay @ 20 Hz 00 351 Hz 7° 01 237 Hz 9° 10 173 Hz 11° 11 937 Hz 5° |
