Reading Trace Data On-the-fly

Trace data can be read while executing a program. However, this is not possible during
sampling. Disable the trace function or terminate tracing before attempting to read trace
data.

■ Reading Trace Data On-the-fly in Single Trace

To disable the trace function, use the DISABLE TRACE command. Check whether or not the trace function
is currently enabled by executing the SHOW TRACE command with /STATUS specified, or by using the
built-in variable, %TRCSTAT.
Tracing terminates when the delay count ends after the sequencer has terminated. If Not Break is specified
here, tracing terminates without a break operation. It is possible to check whether or not tracing has
terminated by executing the SHOW TRACE command with /STATUS specified, or by using the built-in
variable, %TRCSAMP.
To read trace data, use the SHOW TRACE command; to search trace data, use the SEARCH TRACE
command. Use the SET DELAY command to set the delay count and break operation after the delay count.

If the CLEAR TRACE command is executed with the trace ending state, trace data sampling can be re-
executed by re-executing the sequencer from the beginning.
