1. This bit must be set to '0' for the correct operation of the device.

HPCF_XL_[2:0]

Accelerometer LPF2 and HP filter configuration and cutoff setting. Refer to Table 68.

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

(0: disabled, 1: enabled(1))

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 25.

LOW_PASS_ON_6D

LPF2 on 6D function selection. Refer to Figure 25. 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.
