HPCF_XL_[2:0] Accelerometer LPF2 and HP filter configuration and cutoff setting. Refer to Table 65.
HP_REF_
MODE_XL
Enables accelerometer high-pass filter reference mode (valid for high-pass path - HP_SLOPE_XL_EN bit
must be ‘1’). Default value: 0
(1)
(0: disabled, 1: enabled)
FASTSETTL
_MODE_XL
Enables accelerometer LPF2 and HPF fast-settling mode. The filter sets the second samples after writing
this bit. Active only during device exit from power- down mode. Default value: 0
(0: disabled, 1: enabled)
HP_SLOPE_
XL_EN
Accelerometer slope filter / high-pass filter selection. Refer to Figure 24. Accelerometer block diagram.
XL_FS_MODE
Accelerometer full-scale management between UI chain and OIS chain
(0: Old full-scale mode. When XL UI is on, the full scale is the same between UI/OIS and is chosen by the UI
CTRL registers; when XL UI is in PD, the OIS can choose the FS.
1: New full-scale mode. Full scales are independent between the UI/OIS chain but both bound to 8 g.)
LOW_PASS
_ON_6D
LPF2 on 6D function selection. Refer to Figure 24. Default value: 0
(0: ODR/2 low-pass filtered data sent to 6D interrupt function;
1: LPF2 output data sent to 6D interrupt function)
1. When enabled, the first output data have to be discarded.
