Using Event Condition restricts the condition; the following three items are set as the internal trace
conditions.

Trace acquisition

Acquisition Information
Acquires the internal trace until the Event Condition is satisfied. (The
trace content is displayed in the [Trace] window after a trace has been
halted. No break occurs in the user program.)
Acquires only the data access where the Event Condition is satisfied.
Traces the period from the satisfaction of Event Condition 5 to the
satisfaction of Event Condition 4.
To restrict trace acquisition to access for only a specific address or specific function of a program,
an Event Condition can be used. Typical examples are described below.
• Example of halting a trace with a write access (M-bus) to H’FFF80000 by the user program as
a condition (trace halt):
Set the condition to be acquired on [I-Trace mode].
Set the following in the [Event Condition 1] or [Event Condition 2] dialog box:
Address condition: Set [Address] and H’FFF80000.
Bus state condition: Set [M-Bus] and [Write].
Action condition: Deselect the [Acquire Break] checkbox and select [Stop] from the
[Acquire Trace] list box.
• Example of acquiring the write access (M-bus) only to H’FFF80000 by the user program (trace
acquisition condition):
Select [M-Bus & Branch] from [Type] and enable [Write] on [Acquisition].
Set the following in the [Event Condition 1] or [Event Condition 2] dialog box:
Address condition: Set [Address] and H’FFF80000.
Bus state condition: Set [M-Bus] and [Write].
Action condition: Deselect the [Acquire Break] checkbox and select [Condition] from the
[Acquire Trace] list box.
For the trace acquisition condition, the condition to be acquired by Event Condition should be
acquired by [I-Trace mode].
• Example of acquiring a trace for the period while the program passes H’1000 through H’2000
