CTRL1_OIS (70h)

OIS configuration register. Primary interface for read-only (r); only Aux SPI can write to this register (r/w).

OIS_EN_SPI2

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

Table 154. 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. OIS outputs are available through SPI2 in registers OUTX_L_A (28h) and

OUTX_H_A (29h) - OUTZ_L_A (2Ch) and OUTZ_H_A (2Dh).

Note: OIS_EN_SPI2 must be enabled (i.e. set to ‘1’) to enable also 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 Mode 4 (mode4_en = 1).

When the OIS chain is enabled, the OIS outputs are available through the SPI2 in registers OUTX_L_G

(22h) and OUTX_H_G (23h) through OUTZ_L_A (2Ch) and OUTZ_H_A (2Dh) and STATUS_REG (1Eh) /

STATUS_SPIAux (1Eh), and LPF1 is dedicated to this chain.

DEN mode selection can be done using the LVL1_OIS bit of register CTRL1_OIS (70h) and the LVL2_OIS bit of

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