Table 153. CTRL3_OIS register description

FS[1:0]_XL_OIS

Selects accelerometer OIS channel full-scale. See Table 154.

FILTER_XL_

CONF_OIS_[2:0]

Selects accelerometer OIS channel bandwidth. See Table 155.

ST[1:0]_OIS

Selects gyroscope OIS chain self-test. Default value: 00

Table 156 lists the output variation when the self-test is enabled and ST_OIS_CLAMPDIS = '1'.

(00: Normal mode;

01: Positive sign self-test;

10: Normal mode;

11: Negative sign self-test)

ST_OIS_

CLAMPDIS

Disables OIS chain clamp

(0: All OIS chain outputs = 8000h during self-test;

1: OIS chain self-test outputs as shown in Table 156.

Note:

XL_FS_MODE bit is in CTRL8_XL (17h).

Note:

When the accelerometer full-scale value is selected only from the UI side it is readable also from the OIS side.
