Table 2.14 AUD Trace Acquisition Mode
Type Mode Description
Continuous
trace occurs
Realtime trace When the next branch occurs while the trace information is
being output, all the information may not be output. The user
program can be executed in realtime, but some trace
information will be lost.
Non realtime
trace
When the next branch occurs while the trace information is
being output, the CPU stops operations until the information
is output. The user program is not executed in realtime.
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.
