4.4.3 Auxiliary GP Digital Inputs/Outputs
All signals are galvanically isolated to the internal ground of the controller. The general purpose
digital inputs have schmitt-trigger characteristics. Table 4.11 lists the threshold voltage levels.
The general purpose digital outputs are designed as open-collector outputs. This means that
the output logic is inverted. Writing a one to an output switches the output transistor on which
leads to a low signal level at the output pin.
