Abort a pending CAN frame transmission.

Since the determinism of CAN depends on the prioritization of frames based on ID, the TCAN4550 CAN controller allows you to abort a pending transmit to replace it with a higher priority ID.

When implementing protocols that require abort, ensure that only one transmit is pending. Call Wait on Transmit Complete before or after each call to CAN Output. If more than one transmit is pending at the time Abort Transmit is called, the Transmit Success Boolean could refer to any one of those pending frames.
