Note:

Mode 4 is enabled when mode4_EN = 1 and OIS_EN_SPI2 = 1 in UI_CTRL1_OIS (70h) / SPI2_CTRL1_OIS

(70h).

The configuration of the accelerometer UI chain is not affected by enabling mode 4.

Accelerometer output values are available in the following registers with ODR at 6.66 kHz:

•

UI_OUTX_L_A_OIS (50h) and UI_OUTX_H_A_OIS (51h) through UI_OUTZ_L_A_OIS (54h) and

UI_OUTZ_H_A_OIS (55h)

•

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)

Accelerometer full-scale management between the UI chain and OIS chain depends on the setting of the

XL_FS_MODE bit in register CTRL8_XL (17h).
