Using the Trace Buffer

The trace buffer allows us to look back over previous H8S/2238 Series MCU operation cycles to see
exactly what the H8S/2238 Series MCU has been doing prior to a specified event (break) such as an Event
breakpoint.

7.12.1

Displaying the Trace Buffer

The trace buffer will display the captured bus cycle and decode the data in the trace window.

•

Open the Trace Window by choosing Trace from the View menu, or click on the Trace Window
button in the toolbar.

The Trace window is displayed, as shown in the following figure.

Figure 7-31
