I try to understand ST's "Dual CAN Bus" implementation in STM32F derivatives. In my given hardware, I can only use the CAN2 (Slave) module, but I would like to use all "filter features" of the CAN1 (Master) module.

So how can I activate the "dual mode"? Do I just have to enable CAN1 clock or is there anything else to do?

For further infomation please see reference manual from page 1483 (ref_manual)

Thanks :)
