XMR … Transmit Message Repeat
XDU/EXE … Transmit Data Underrun/Extended Transmission End

The actual frame has been aborted with IDLE, because the XFIFO holds no further data,
but the frame is not yet complete!
In extended transparent mode, this bit indicates the transmission-end condition.
the HSCX has received a negative acknowledgement in auto-mode,
or a collision has occurred after sending the 32nd data byte of a message in a bus
configuration.
or CTS (transmission enable) has been withdrawn after sending the 32nd data byte of a
