This register contains the data read from the path 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]) contains the data read from either the transmit or receive path
trace buffer after an indirect read operation is completed. The data that is written to a buffer
is set up in this register before initiating the 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.
