1.1

Power-down mode

When the device is in power-down mode, almost all internal blocks are switched off to

minimize power consumption. Digital interfaces (I2C and SPI) are still active to allow

communication with the device. The content of the configuration registers is preserved and

output data registers are not updated, therefore keeping the last data sampled in the

memory before switching to power-down mode.

1.2

Normal mode

In normal mode, data are generated at the selected output data rate (ODR) through the

ODR bits. Nine different ODR configurations are available in normal mode, from 3.125 Hz to

1600 Hz.

1.3

Switch mode timing

Turn-on times of the LIS3DSH accelerometer are shown in Table 3. Their values depend on

the ODR and bandwidth selected.
