DC bus sensing configuration

The low side resistor R1 for the DC bus sensing resistor divider on the controller board EVAL-M1-101T is 13.3kΩ,

and should be configured in MCEWizard as shown in Figure 17. For the high side resistor value, please refer to

the Application Note of the corresponding power board.
