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 IECR.INCG), stand-by mode and limp home mode. Channel 0 and the
external drivers can be activated only via the SPI-bit OUT.OUTn in direct drive mode. The inputs are linked directly
to the channels according to:

6.2.2
To activate the assigned drive function the register bit IECR.INCG needs to be set. In this mode all output
channels can be activated via the input pins. Channel 2, 3 and the two external drivers are assigned to only one
input pin. The following mapping is used:

The power DMOS switches with a dedicated slope, which is optimized in terms of EMC emission. Defined slew
rates and edge shaping allow lowest EMC emissions during PWM operation at low switching losses.
