LIS2DE12 - What is low-power mode

Hi,Can some one explain what is low power mode. It is mentioned in page 45 in the data sheet. But no where it is explained. I would like it to work in low power mode and wake up on certain condition (also cause INTERRUPT) and go back to low power mod...

LIS2DE12: Movement detection over interrupt question

Hello there,I have a question about this sensor. I'll be using it as a low-power device on a PIC, which is most of the time in sleep mode, and will wake up on interrupts from various devices. I want to configure this sensor so it will notify the PIC ...

LIS2DW12 MISO low output voltage

Hi, We have a LIS2DW12 and a S2-LP setup on the same PCB, both using SPI.We have found that the LIS2DW12 has a high of 1.16V on the MISO with Vio = 3.3V. We can see that the correct bits are sent on the MISO, the voltage is just too low for the micro...
