Abort CAN Controller transmission

Hi,

 

Is there a way to clear the Transmit FIFO of the CAN controller for the Xilinx Zynq Ultrascale+ XU9?

 

I wish to clear of all pending transmissions from the FIFO that are not currently active on the CAN bus (ie. they do not have arbitration).

 

Similarly, is there a way to clear/abort a message in the TXHPB high priority buffer that is not currently active on the CAN bus?

 

I really don't want to have to reset the whole CAN module as I could miss receptions.

 

Regards,

Dale
