Big/Little Endian data selection. Default value: 0
(0: output LSbyte at lower register address;
1: output LSbyte at higher register address)
Enables level-sensitive trigger mode on OIS chain. Default value: 0
SPI1 3- or 4-wire mode. Default value: 0
(0: 4-wire SPI1; 1: 3-wire SPI1)
Enable accelerometer OIS chain. Default value: 0
(0: disable; 1: enable)
Gyroscope OIS chain full-scale selection.
(00: 245 dps;
01: 500 dps;
10: 1000 dps;
11: 2000 dps)
Selects gyroscope’s UI chain full scale 125 dps
(0: FS selected through bits FS[1:0]_OIS_G;
1 = 125 dps)
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.
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.
