UI_CTRL1_OIS (70h)

OIS configuration register. The primary interface can write this register when the OIS_CTRL_FROM_UI bit in the

FUNC_CFG_ACCESS (01h) register is equal to 1 (Primary IF Full control mode); this register is read-only when

the OIS_CTRL_FROM_UI bit is equal to 0 (SPI2 Full control mode) and shows the content of the

SPI2_CTRL1_OIS (70h) register.

Table 178. UI_CTRL1_OIS register description

LVL1_OIS

Enables level-sensitive trigger mode on OIS chain. Default value: 0

SIM_OIS

SPI2 3- or 4-wire interface. Default value: 0

(0: 4-wire SPI2;

1: 3-wire SPI2)

Mode4_EN

Enables accelerometer OIS chain. When the OIS_CTRL_FROM_UI bit in the FUNC_CFG_ACCESS (01h)

through the primary interface in registers 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) and UI_STATUS_REG_OIS (49h).

Note: OIS_EN_SPI2 must be enabled (i.e. set to ‘1’) to enable also the XL OIS chain.

FS[1:0]_G_OIS

Selects gyroscope OIS chain full-scale

(00: 250 dps;

01: 500 dps;

10: 1000 dps;

11: 2000 dps)

FS_125_OIS

Selects gyroscope OIS chain full-scale 125 dps

(0: FS selected through bits FS[1:0]_OIS_G;

1: 125 dps)

OIS_EN_SPI2

Enables OIS chain data processing for gyro in Mode 3 and Mode 4 (mode4_en = 1) and accelerometer data

in and Mode 4 (mode4_en = 1).

When the OIS_CTRL_FROM_UI bit in FUNC_CFG_ACCESS (01h) register is equal to 1 (Primary IF Full

control mode enabled), the gyroscope OIS outputs are available through the primary interface in registers

UI_OUTX_L_G_OIS (4Ah) and UI_OUTX_H_G_OIS (4Bh) through UI_OUTZ_L_G_OIS (4Eh) and

UI_OUTZ_H_G_OIS (4Fh)and UI_STATUS_REG_OIS (49h), and LPF1 is dedicated to this chain.

DEN mode selection can be done using the LVL1_OIS bit of register UI_CTRL1_OIS (70h) and the LVL2_OIS bit

of register UI_INT_OIS (6Fh).

DEN mode on the OIS path is active in the gyroscope only.
