DEN_LH_OIS
Polarity of DEN signal on OIS chain
(0 = DEN pin is active low;
1 = DEN pin is active high)
FS[1:0]_XL_OIS
Accelerometer OIS channel full-scale selection
00 = 2g (default)
01 = 16g
10 = 4g
11 = 8g
These two bits act only when the accelerometer UI chain is in
power-down, otherwise the accelerometer FS value is selected
only from the UI side (but it is readable also from the OIS side).
FILTER_XL_CONF_OIS [1:0] Accelerometer OIS channel bandwidth selection (see Table 223)
ST[1:0]_OIS
Gyroscope OIS chain self-test selection
Table 224 lists the output variation when the self-test is enabled
and ST_OIS_CLAMPDIS = '0'
00 = Normal mode (default)
01 = Positive sign self-test
10 = Normal mode
11 = Negative sign self-test
ST_OIS_CLAMPDIS
OIS chain clamp disable
0 = All OIS chain outputs = 8000h during self-test
1 = OIS chain self-test outputs as shown in Table 224
