Table 62. CTRL8_XL register description

High-resolution mode for accelerometer enable. Default value: 0.

(0: disabled; 1: enabled) Refer to Table 63

DCF_XL

[1:0]

Accelerometer digital filter (high-pass and low-pass) cutoff frequency selection: the

bandwidth of the high-pass filter depends on the selected ODR. Refer to Table 63

HPM_XL
