3.5 MCU-FlexRay CC Connection at SK-91F467-FLEXRAY
The FlexRay communication controller MB88121 provides different communication modes to
a microcontroller. The MB88121 has different pin functions in its communication modes.
Therefore it is possible to connect the CC in different ways to the MCU, to evaluate the
different communication modes.
