STM32F427 CAN protocol

Hi

I am working on Redesign project. The existing controller is STR912FAWx. In this controller, CAN protocol has CAN_IDR register to identify the message objects causing the interrupt.

Similarly, in STM32F4 do we have CAN message object to identify the interrupt? Or is there any other way to identify the CAN message object?

Kindly do the needful.
