(2) Trace acquisition mode
The AUD trace function has the following modes to acquire a trace.
Table 2.2 shows the AUD trace acquisition mode that can be set in each trace function.
Table 2.2 AUD Trace Acquisition Mode
Type Mode Description
Continuous
trace occurs
Realtime trace When the trace information is being generated intensively
that the output from the AUD pin incapable of keeping up, the
CPU temporarily suspends the acquisition of trace
information. Therefore, although the user program is run in
real time, the acquisition of some trace information might not
be possible.
Non realtime
trace
When trace information is being generated so intensively that
the output from the AUD pin is incapable of keeping up, CPU
operations are temporarily suspended and the output of trace
information takes priority. In such cases, the realtime
characteristics of the user program are lost.
Trace buffer
full
Trace continue This function overwrites the latest trace information to store
the oldest trace information.
Trace stop After the trace buffer becomes full, the trace information is no
longer acquired. The user program is continuously executed.
