AUD Trace Functions: This function is operational when the AUD pins of the MCU are

connected to the emulator. Table 3.15 shows the AUD trace acquisition mode that can be set in

each trace function.

Table 3.15 AUD Trace Acquisition Mode

Type Mode Description

Continuous

trace occurs

Realtime trace When the next branching 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 branching 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 writes the latest trace information on the oldest

information to store the latest trace information.

Trace stop After the trace buffer becomes full, the trace information is no

longer acquired. The user program is continuously executed.

Break A break occurs when the trace buffer becomes full.

AUD trace

function used

Enable free trace When this box is checked, the emulator ignores the AUD

eventpoint setting and acquires all trace information.

Time stamp clock The resolution of the timer for timestamps can be specified.

Select 20 ns, 100 ns, 400 ns, or 1.6 μs.

To set the AUD trace acquisition mode, click the [Trace] window with the right mouse button and

select [Setting] from the pop-up menu to display the [I-Trace/AUD-Trace acquisition] dialog box.

The AUD trace acquisition mode can be set in the [AUD mode1], [AUD mode2], or [AUD
