The high-side power stages are built by N-channel vertical power MOSFETs (DMOS) with charge pumps. There
are four channels implemented in the device. Channels can be switched on via an input pin (please refer to

The outputs of the SPOC - BTS6480SF can be activated either via the SPI register OUT.OUTn or via the dedicated
input pins. There are two different ways to use the input pins, the direct drive mode and the assigned drive mode.
The default setting is the direct drive mode. To activate the assigned drive mode the register bit IECR.INCG
needs to be set.
Additionally, there are two ways of using the input pins in combination with the OUT register by programming the
IECR.COL parameter.
