I am looking for a way to change the CAN-port-pins from port 4 to port 8 (because of the need of all adress-pins). The Infineon doc talks about register C1PCIR (3 IPC Bits). When I set these bits from 000 to 010, (Instruction C1PCIR = 0x200) like the manual says, the KEIL-CAN-Debugger shows me after step over, that the old contents of 0xFF00 is repeatingly stored in the register. Whats wrong? Has anybody routet the CAN-Pins to another location than default? Thanks a lot... Mike
