Can"B" (Jp: 27, 28); I²C Pull-Up (Jp: 46, 47); C-Pin Capacitor - Fujitsu F2MC-16FX Series User Manual

3.10 CAN"B" (JP: 27, 28)

One high-speed CAN-transceiver can be connected to the microcontroller's CAN interface.
JP27, JP28 connects a CAN-port to the CAN-transceiver (U8, X11).
JP33
JP27 (CAN"A"TX)
JP28 (CAN"A"RX)
JP33 (VCC CAN B)
3.11 I²C Pull-Up (JP: 46, 47)
Two 10k Ohm resistors can be connected to the SDA0 and SCL0 lines.
JP46 (SDA0)
JP47 (SCL0)

3.12 C-Pin Capacitor

For normal operation the C-pin must be connected to two capacitors. For test purposes you
can disconnect these two capacitors.
