Encoder/Hall Sensor Interface

The motor control application can read position or speed from up to two independent encoders or HALL
sensors. The on-board interfaces provides the 5V power supply voltage to supply the sensors. The Hall
interface inputs are designed to support an open collector as well as push-pull Hall sensors outputs, see
Figure 7. A single pole RC low pass filter is present to reduce a signal noise.
