2. Input signals are active high. Pull-down resistors are not inserted on the EVAL-M1-05-65D board and need to be
assembled on control cards. iMOTION™ MADK control cards are already equipped with pull-down resistors.
3. Gate Kill signal (GK) is pulled low during over current condition. Chapter 6.6 explains the details of this circuit.
