Hall Sensor and Encoder Connectors
The KIT_XMC4400_DC_V1 provides two pairs of HALL and incremental encoder connectors as indicated in
Figure 13. The encoder interface connector provides a differential input which is transformed into single ended
signals by an interface IC. The HALL sensor interface provides a pull-up resistor for each HALL sensor signal as
well as power supply for the HALL sensors
Figure 13
Hall Sensor and Encoder Connectors
Both the HALL and the encoder signals are connected to the same POSIF interface. The ENENC-signal is used
to either enable the output signals of the encoder IC or to activate the power supply and pull-up resistor supply
of the HALL sensor interface. As a result, both interfaces can be connected at the same time and the user can
select by software which interface to use. Figure 14 shows the HALL sensor and encoder interface circuitry of
interface 0. Please refer to Table 4 for details on pin and peripheral assignment.
