FIFO data
R 200010504 shows which of the messages boxes has received the latest
new CAN message. Read access to R 200010504 removes the value which
has been read last from the FIFO buffer. This access decrements the value of
R 200010503 by one.
Note:
Each read access to this register, even via an active JetSym setup screen,
decrements the number of received CAN messages.
