STM32G474 release fifo

[CDril]

Hi all,

I used long time STM32F103 and there was the possibilty to release the CAN Fifo by writing CAN_RF0R, resp. CAN_RF1R register. For G474 I didn't find this possibilty. Has someone any idea how to release the receive buffer or is the only option to check if something is in and read out?
