G_HM_

MODE

HP_EN_G

HPM1_G

HPM0_G

0(1)

USR_OFF_

ON_OUT

0(1)

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

G_HM_MODE

Disables high-performance operating mode for gyroscope. Default: 0

(0: high-performance operating mode enabled;

1: high-performance operating mode disabled)

HP_EN_G

Enables gyroscope digital high-pass filter. The filter is enabled only if the gyroscope is in HP mode. Default value: 0

(0: HPF disabled; 1: HPF enabled)

HPM_G[1:0]

Gyroscope digital HP filter cutoff selection. Default: 00

(00: 16 mHz;

01: 65 mHz;

10: 260 mHz;

11: 1.04 Hz)

USR_OFF_ON_OUT

Enables accelerometer user offset correction block; it's valid for the low-pass path - see Figure 20 . Default value: 0

(0: accelerometer user offset correction block bypassed;

1: accelerometer user offset correction block enabled)

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 61.

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 22.

LOW_PASS_ON_6D

LPF2 on 6D function selection. Refer to Figure 22. 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.
