4.1.3. Current and Voltage Sensing
For sensor-less control, the motor phase currents IU1, IV1, IW1 and DC bus voltage VB1 are sampled and
measured simultaneously by the 4 inputs of the 12-Bit analog to digital converter unit S12ADA.
4.1.4. Hall Sensor Interfacing
For hall sensor support three input capture pins MTIOC0A, MTIOC0B and MTOIC0C of timer channel
MTU3-0 are used and the interface connector J9 shown in Figure 5 below.
