So the total pull-up resistance calculates to be 2.605kΩ. The typical value of RNTC at 100°C is 5.388kΩ for IPM IKCM10H60GA which is used in EVAL-M1-CM610N3. If the setting temperature is 100° C, the shutdown value should be 2.22V. Figure 18 External temperature sense input configuration in MCEWizard

5.2.3 VSP analog input control mode and PGout configuration
VSP analog input control mode can be configured in the options page for MCEWizard by clicking and selecting in the pull down list marked with red box as shown in Figure 19. Figure 19 Analog VSP control input mode configuration There are three input thresholds (percentage of controller supply voltage VDD) used to define the relationship between VSP input voltage and TargetSpeed. 1. T1 (Input threshold for motor start): if the VSP analog voltage is above this threshold, motor will start 2. T2 (Input threshold for motor stop): if the VSP analog voltage is below this threshold, motor will stop 3. T3 (Input threshold for Max RPM): if the VSP analog voltage is higher or equal to this threshold, TargetSpeed will be 16384 which is Max RPM.

By default, VDD is 3.3V for EVAL-M1-101T. The input of VSP and PGOUT (pulse generation output) should be limited within the voltage range of 0 and 3.3V. While for some application, PGOUT should be connected to speed measurement circuit. The evaluation board EVAL-M1-101T provides FG (Frequency Generation) signal with an open drain structure controlled by PGOUT as shown in Figure 23. And FG signal can be pull up to 30V. The frequency of FG is the same as PGOUT, and the calculation equation for motor speed is the same.
