This register contains the data read from the section trace message buffer after a read operation
or the data to be written into the buffer before a write operation.
D[7:0]:
The indirect data bits (D[7:0]) reports the data read from a message buffer after an indirect
read operation has completed. The data to be written to a buffer must be set up in this
register before initiating an indirect write operation.
The current and accepted message pages should be read at least twice and the results of the
successive reads compared for consistency. The section trace message buffer keeps
overwriting these message pages and consequently the result of a read can be composed of
multiple messages.
