Trace Buffer Data Bits — The trace buffer data bits contain the data of the trace buffer. This register can be read
only as a word read. Any byte reads or misaligned access of these registers will return 0 and will not cause the
trace buffer pointer to increment to the next trace buffer address. The same is true for word reads while the
debugger is armed. In addition, this register may appear to contain incorrect data if it is not read with the same
capture mode bit settings as when the trace buffer data was recorded (See

Buffer”). Because reads will reflect the contents of the trace buffer RAM, the reset state is undefined.
