The current sink to ground ensures that the input signal is low in case of an open input pin. The zener diode
protects the input circuit against ESD pulses.
6.2.1
This mode is the default after the device’s wake up and reset. The input pins activate the channels during normal
operation (with default setting of bit ICR.INCG), stand-by mode and limp home mode. Channel 0 can be activated
only via the SPI-bit OUTL.OUT0 in direct drive mode. The inputs are linked directly to the channels according to:

To activate the assigned drive function the register bit ICR.INCG needs to be set. In this mode all output channels
can be activated via the input pins. Channel 2 and 3 are assigned to only one input pin. The following mapping is
used:
