The accelerometer filtering chain when mode 3 is enabled is illustrated in the following figure.

Note:

The accelerometer OIS chain is enabled by setting the OIS_XL_EN bit to 1 in the UI_CTRL1_OIS (70h) /

SPI2_CTRL1_OIS (70h) register.

The configuration of the accelerometer UI chain is not affected by enabling/disabling the accelerometer OIS

chain, with one exception: accelerometer normal operating mode (OP_MODE_XL_[2:0] = 111 in the CTRL1

(10h) register) cannot be used when the accelerometer OIS chain is enabled.

Accelerometer output values are available in the following registers with ODR at 7.68 kHz:

•

UI_OUTX_L_A_OIS_DualC (34h) and UI_OUTX_H_A_OIS_DualC (35h) through

UI_OUTZ_L_A_OIS_DualC (38h) and UI_OUTZ_H_A_OIS_DualC (39h)

•

SPI2_OUTX_L_A_OIS (28h) and SPI2_OUTX_H_A_OIS (29h) through SPI2_OUTZ_L_A_OIS (2Ch) and

SPI2_OUTZ_H_A_OIS (2Dh)
