21.1.9 Single Transmission Try Functionality
Single transmission try functionality is controlled individually for each message object by
bit STT in register MSGFGCRn. If the single transmission try functionality is enabled, the
transmit request flag TXRQ is reset immediately after the transmission of a frame related
to this message object has started. Thus, a transmit frame is only transferred once on
the CAN bus, even if it has been corrupted by error frames.
Note: A message object must be tagged valid by bitfield MSGVAL in order to enable the
transmission of the respective frame.
