Need to detect fault signals coming from each transceiver A and transceiver B on CAN1.

Transceiver: TCAN1043HGDQ1 Product page Datasheet

Need to understand types of fault signals generated by the transceiver
What should be the logic for reacting to fault interrupts?
Where in NuttX code should it be?
FlexCAN driver? Doesn't make sense because it is the bus interface on the board....
Or a separate driver? In that case, how should the transceiver driver interact with FlexCAN driver?
