LIS3DSH, SDO Pullup Register

Hello,

We have been using the LIS3DH for some time and recently acquire some LIS3DSH' as well.

With both modules there is an internal pull-up for the SDO pin, and with the LIS3DH there is a register to control this pullup:
CTRL_REG0

I am not able to find a similar register for the LIS3DS, and that register address is referenced as something else.
I recall that in earlier versions of the LIS3DH datasheet, this register was not provided, but added in later revisions.

Is there some unlisted register for the LIS3DS to disable this internal pull-up? Or some other method?

Thankyou.

    Hi @videojames ,

    That register is not available for LIS3DSH.

    However, not that the LIS3DSH is an obsolete product for ST and out of production. I suggest you to use only the LIS3DH.
