Auxiliary SPI configurations

Auxiliary SPI configurations

When the ISM330DLC is configured in Mode 3 and Mode 4, the auxiliary SPI can be

connected to an auxiliary host (OIS). In this interface, the SPI can write only to the dedicated

registers INT_OIS (6Fh), CTRL1_OIS (70h), CTRL2_OIS (71h), CTRL3_OIS (72h).

Gyroscope filtering

The gyroscope filtering chain is illustrated in the following figure.

Figure 21. Gyroscope chain

Note:

HP_EN_OIS is active to select HPF on the auxiliary SPI chain only if HPF is not already

used in the primary interface.

The auxiliary interface needs to be enabled in CTRL1_OIS (70h).

Gyroscope output values are in registers 22h to 27h with selected full scale (FS[1:0]_G_OIS

bit in CTRL1_OIS (70h)) and ODR at 6.66 kHz.

LPF1 configuration depends on the setting of the FTYPE_[1;0] _OIS bit in register

CTRL2_OIS (71h).
