Accelerometer low-pass filter LPF2 selection. Refer to Figure 7.

HPCF_XL[1:0]

Accelerometer slope filter and high-pass filter configuration and cutoff

setting. Refer to Table 68. It is also used to select the cutoff frequency of the

LPF2 filter, as shown in Table 69. This low-pass filter can also be used in the

6D/4D functionality by setting the LOW_PASS_ON_6D bit of CTRL8_XL

(17h) to 1.

HP_SLOPE_XL_EN Accelerometer slope filter / high-pass filter selection. Refer to Figure 7.

LOW_PASS_ON_6D Low-pass filter on 6D function selection. Refer to Figure 7.
