CHAPTER 2 DEPENDENCE FUNCTIONS

2.4.5.5

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

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 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.

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.
