    1. First you'll need to configure the following parameters before you can run MPET on the MCF8329A
      1. BASE_CURRENT
      2. MAX_SPEED
      3. MOTOR_RES
      4. MOTOR_IND
    2. Next, you might need to configure the following parameters to ensure MPET KE measurement runs successfully
      1. MPET_OPEN_LOOP_SLEW_RATE
      2. MPET_OPEN_LOOP_CURR_REF
      3. Please refer to Datasheet section 7.3.15 Motor Parameter Extraction Tool (MPET) for more details.
