MC33772BSPIEVB, using question about MC33772x EvalGUI

We are using FRDM-KL25Z as MCU development platform to operate MC33772x EvalGUI.

When we click the save configuration, all the thresholds and Regitors are reset to original values. 

We want to know what the steps to save configuration by using GUI.

And the units of OTs setting in thresholds are degree C, however the measurements are voltage.

What is the corresponding relationship between temperature and voltage?

Dear **bleep**,

the save configuration is not meant for saving the register settings, but for saving the interface and selected port. Please click the info button and then the Open docu and it will open for you a user guide to the GUI.

For the GPIOs used for temperature measurements, please refer to the section 9.16.4 in the MC33771B datasheet. You need to set the GPIOs as digital inputs and then you need to set overtemperature and undertemperature thresholds in the registers described in the 9.16.4 section. 

In the MEAS_ANx registers are the conversion values.
