CTRL_OIS (70h)

Only SPI2 can write to this register (r/w).

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

the LVL2_OIS bit of register INT_OIS (6Fh).

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

Table 216. CTRL_OIS register description

BLE_OIS

Big/Little Endian data selection. Default value: 0

(0: output LSbyte at lower register address;

1: output LSbyte at higher register address)

LVL1_OIS

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

SIM_OIS

SPI1 3- or 4-wire mode. Default value: 0

(0: 4-wire SPI1; 1: 3-wire SPI1)

OIS_XL_EN

Enable accelerometer OIS chain. Default value: 0

(0: disable; 1: enable)

FS[1:0]_

G_OIS

Gyroscope OIS chain full-scale selection.

(00: 245 dps;

01: 500 dps;

10: 1000 dps;

11: 2000 dps)

FS_125

_OIS

Selects gyroscope’s UI 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.

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

registers 22h-27h and 1Eh register, and LPF1 is dedicated to this chain.
