Controlling the Sensor Measurement Interface (SMI) in FXTH870911

TKB — Tue, 03 Feb 2026 20:59:43 GMT

Is there a way for me to control the state of the Sensor Measurement Interface (SMI) i.e. turn it OFF or ON when required or is it done by the firmware defined subroutines only?

Exploring this path for additional power savings if possible.

Thanks

Hi Tushar,

This is handled by the TPMS_READ routines: the entire measurement chain is enabled at the beginning of the routine and disabled at the end. So when the program exits the routine, everything has been turned off.

Best regards,

Tomas
