Setting Trace
To perform a trace, follow steps (1) to (3) below. When a program is executed after
completion of the following steps, trace data is sampled.
(1) Enable the trace function.
(2) The event and the sequencer are set.
(3) Perform trace buffer full break setup.
■ Setting Trace
To perform a trace, complete the following setup steps. When a program is executed after completion of the
steps, trace data is sampled.
1) Enable the trace function.
Enable the trace function using the ENABLE TRACE command.
To disable the trace function, use the DISABLE TRACE command.
The trace function is enabled by default when the program is launched.
2) Set up the event and the sequencer.
Use of the trace trigger allows control of the trace sampling, making full use of the limited-size trace
buffer. Such setups should be performed on a necessary base.
The trace trigger can specify the start/stop of trace sampling with the trigger hit as the reason.
When the trace trigger is used, setup is performed by inputting the SET TRACE/TRIGGER command.
3) Perform trace buffer full break setup.
A break can be invoked when the trace buffer becomes full.
To perform setup, use the SET TRACE command. This break feature is disabled when the program
starts. To confirm the setting, use SHOW TRACE/STATUS.
Table 2.5-5 shows trace related commands in single trace.
