The high-side power stages are built by N-channel vertical power MOSFETs (DMOS) with charge pumps. There
are six channels implemented in the device. Each channel can be switched on via an input pin or via SPI register
OUT. Channels 0, 1 and 2 provides a load type configuration for bulbs or LEDs in register PLCR. The load type
configuration is allowed to be changed in OFF-state only.

There are two ways of using the input pins in combination with the OUT register by programming the HWCR.PWM
parameter.

PLCR.PWM = 0: A channel is switched on either by the according OUT register bit or the input pin.
PLCR.PWM = 1: A channel is switched on by the according OUT register bit only, when the input pin is high. In
this configuration, a PWM signal can be given to the input pin and the channel is activated by the SPI register
OUT.
