Power Stages
The zener diode protects the input circuit against ESD pulses. The current sink to ground ensures that the input
signal is low in case of an open input pin.

Input Status Monitor
The level of the input stage can be monitored via the input status monitor. The input status is indicated in the OUT
register for the available input pin. After setting the bit SWCR.SWR = 1_B, the readout of OUT.INSTn shows the state
of the input pins.
