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.
JP1 Connects MCU INT6 or MCU A10 to CC pin 35 (INT2 / A10)
