The CAN and FlexRay control signals (Error, Enable, Wake and STB) are shared.
So, it is not possible to use the same CAN and FlexRay channel simultaneously.

FlexRay wake up

The Starter Kit offers the possibility to power on the three power supplies (1.2 V,
3.3 V, 5 V) by the FlexRay transceivers in case a FlexRay wake up procedure is
executed. The connections between the FlexRay transceivers are made by CN1.
For further information, please take a look into the schematics.
