Does the lis2dw12 sensor reset triggered via SOFT_RESET bit also reset the trimming parameters?

[MBoch.2]

Or in other words if we are triggering SOFT_RESET,  is this necessary after that also explicitly re-read the trimming parameters  via BOOT  in CTRL2 register? Or this soft reset does not affect the calibration registers.

Background: 

We use different modes(ODR, with/without FIFO,LP/HP ) of lis2dw12 sensor and  when switching we are  triggering SOFT_RESET(CTRL2)  just to make sure that all configuration is in the default state before changing modes. The question comes up: is this necessary to trigger the BOOT as well on this stage to re-read calibration settings or is this not mandatory. 

Thanks in advance!

Hi @MBoch.2 ,

If you want to reset the calibration register you need a BOOT, otherwise if you want to reset the CTRL registers a soft_reset is fine.

Hi @Federica Bossi​ ,

Thanks a lot for your reply, just to make sure:

Can you confirm that soft_reset does not affect the calibration registers and will not reset them?

Normally we don't want to touch calibration data by  soft_reset - our goal is to reset only control registers.

Hi @MBoch.2 ,

Yes, the BOOT is the one that affects the calib reg.
