7.10.2 Digital Outputs
The table below describes the pin out of the output pins, see chapter 5.2.1 for detailed specification of
the output channels. The digital outputs are high-side switches and require an external supply between
pin 1 and pin 2 for operation. The next chapter shows an example wiring for a motor-holding brake.
