The signal interface is responsible for handshaking with the message queue and registers. It is also
responsible for requesting new messages from the message queue. A message is always requested from
the message queue if the message queue is not empty, the message buffer is available and a higher priority
message is not requesting to be transmitted. The rate at which data is removed from the queue depends on
the average message length, the number of MDO signals, and the MCKO clocking rate.
24.7.3
Message formatting is performed in the signal interface block. The following priority scheme is
implemented for messages sent to the signal output formatter block, with 1 being the highest priority and
5 being the lowest priority:
