Could you describe difference in use FIFO0 and FIFO1 for CAN1 and CAN2 in stm32f4 mcu? For example if I configure CAN2 for receive in FIFO0 and configurate filters 14 all work success, but if I try use FIFO1 with CAN2 no interrupt CAN2 happen in receive in this case. CAN0 need use with FIFO0 and CAN2 need use with FIFO1 if big data transfer happen, isn't it(or what case when need use separately FIFO for CAN1 and CAN2)?
