PRODUCTION DATA.
The FlexRay Transfer Unit is able to transfer data between the input buffer (IBF) and output buffer (OBF) of the communication controller and the system memory without CPU interaction.
Because the FlexRay module is accessed through the FTU, the FTU must be powered up by the setting bit 23 in the Peripheral Power Down Registers of the System Module before accessing any FlexRay module register.
For more information on the FTU see the device specific technical reference manual.
