24.13.2.2 OTM Queueing
READI implements a queue 32 messages deep for program trace, data trace, and ownership trace
messages. Messages that enter the queue are transmitted via the output auxiliary port in the order in which
they are queued.
NOTE
If multiple trace messages need to be queued at the same time, ownership
trace messages will have the lowest priority.

24.14 RCPU Development Access
This section details the RCPU development access support features of the READI module.
The READI development port provides a full duplex serial interface for accessing existing RCPU user
register and development features including BDM (background debug mode).
