4.5 FlexRay Physical Layer Module Connector (X3, X7)
To use the FlexRay physical layer driver module from TZM (FT1080) there are two special
connectors on board of SK-91F467-FLEXRAY, both for FlexRay channels A and B, to insert
the modules. If the modules FT1080 should be used, it is necessary to disable the RS-485
driver modules (see chapter 3.6).
