LSM6DSO Pins 10 and 11

[Tatmaz]

Hello, we are planning to use LSM6DSO in Mode 1, but PCB is fixed and pins 10 and 11 are connected to GND. This conflicts with LSM6DSO datasheet but I was wondering if it is still OK to connect them to GND. Can you clarify on this?

Hi ​@Tatmaz ,

For LSM6DSO Mode 1, pins 10 (OCS_Aux) and 11 (SDO_Aux) are not meant to be tied to GND.
According to the datasheet, pin 10 should be left unconnected, and pin 11 should be left unconnected or tied to VDDIO.
So if your PCB has these pins hard-wired to GND, it is not the recommended configuration and behavior is not guaranteed by ST.
