CTRL8_XL (17h)

Control register 8 (r/w)

Table 57. CTRL8_XL register description

Table 54. CTRL7_G register

0(1)

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

HP_EN_G

HPM1_G

HPM0_G

0(1)

USR_OFF

_ON_OUT

0(1)

HP_EN_G

Enables gyroscope digital high-pass filter. The filter is enabled only if the gyro 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 13. Default value: 0

(0: accelerometer user offset correction block bypassed;

1: accelerometer user offset correction block enabled)

HP_SLOPE

_XL_EN

0(1)

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

LOW_PASS

_ON_6D

HPCF_XL_[2:0]

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

Table 58.

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))

1. When enabled, the first output data have to be discarded.

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 15.

LOW_PASS

_ON_6D

LPF2 on 6D function selection. Refer to Figure 15. Default value: 0

(0: ODR/2 low-pass filtered data sent to 6D interrupt function;

1: LPF2 output data sent to 6D interrupt function)
