3.6.3 FT1080 Control Settings (S6)
The DIP switch S6 is used to set EN, WAKE and nSTB signals of the FlexRay physical layer
driver modules from TZM (FT1080). The control signals can also be connected with jumper
to the MCU to give the possibility to set them via user software. Both modules (FT1080) will
be set simultaneously, if JP48-JP50 and JP73-JP75 are closed.
