1.8.13 DM.FIFO_0/DM.FIFO_1/DM.FIFO_2 (FIFO port register)
The DM.FIFO_X registers allow debug software to read trace data from the debug
module FIFO when the trace destination is in either “DM FIFO trace hold” mode or
“circular DM FIFO” mode.
Care should be taken to ensure that trace is not being generated whilst the trace is
being extracted, as this can result in the loss of trace messages.
Trace data is extracted one trace message at a time, 3 registers are used due to the
maximum size of a trace entry (
