6.1

Operating modes

In the LSM6DSO16IS, the accelerometer and the gyroscope can be turned on/off independently of each other

and are allowed to have different ODRs and power modes.

The LSM6DSO16IS has three operating modes available:

•

only accelerometer active and gyroscope in power-down

•

only gyroscope active and accelerometer in power-down

•

both accelerometer and gyroscope sensors active with independent ODR

The accelerometer is activated from power-down by writing ODR_XL[3:0] in CTRL1_XL (10h) while the gyroscope

is activated from power-down by writing ODR_G[3:0] in CTRL2_G (11h). For combo-mode the ODRs are totally

independent.

6.2

Accelerometer power modes

In the LSM6DSO16IS, the accelerometer can be configured in three different operating modes: power-down, low-

power, and high-performance mode. The operating mode selected depends on the value of the XL_HM_MODE

bit in CTRL6_C (15h). If XL_HM_MODE is set to 0, high-performance mode is valid for all ODRs (from 12.5 Hz up

to 6667 Hz).

To enable low-power mode, the XL_HM_MODE bit has to be set to 1. Low-power mode is available for ODRs of

1.6, 12.5, 26, 52, 104, 208 Hz.

6.3

Gyroscope power modes

In the LSM6DSO16IS, the gyroscope can be configured in three different operating modes: power-down, low-

power, and high-performance mode. The operating mode selected depends on the value of the G_HM_MODE bit

in CTRL7_G (16h). If G_HM_MODE is set to 0, high-performance mode is valid for all ODRs (from 12.5 Hz up to

6667 Hz).

To enable low-power mode, the G_HM_MODE bit has to be set to 1. Low-power mode is available for ODRs of

12.5, 26, 52, 104, 208 Hz.
