Flexray "Channel B" (Fr-B) - Fujitsu SK-91465X-100PMC User Manual

3.10 FlexRay "Channel B" (FR-B)

One FlexRay transceiver (X11, X3) can be connected to one of the microcontroller's FlexRay
interface (one channel). In addition further pins of the MCU can be connected to the FlexRay
transceiver for Error-read out feature and power supply switching.
JP58 Connects FlexRay transceiver TXD pin to microcontroller FlexRay TXDA pin
JP59 Connects FlexRay transceiver TXEN pin to microcontroller FlexRay TXENA pin
JP62 Connects FlexRay transceiver RXD pin to microcontroller FlexRay RXDA pin
JP43 Selects FlexRay transceiver STBN pin to Vio or microcontroller pin.
JP66 Selects FlexRay transceiver EN pin to Vio or microcontroller pin.
JP51 Connects FlexRay transceiver ERRN pin to microcontroller pin.
