Viewing Assembly Language Code

While a source file is open, click the right mouse button in the Editor window and choose View Disassembly from the popup

menu. The Disassembly window will be displayed.

The first address shown in the Disassembly window corresponds to the cursor position in the Editor window.

You can also use the View Disassembly button in the Editor window to view code produced by disassembly.

If there is no source file, you can still view the disassembly by one of the following methods.

−

Click on the Disassembly toolbar button [

−

Choose Disassembly from the View menu.

−

Use the “Ctrl + D” shortcut keys.

In this case, the Disassembly window opens with a listing from the position currently indicated by the PC.

The emulator also supports a mixed mode as an optional way to show all source lines from the address where disassembly

started. To view disassembly code in mixed mode, click the View mixed mode button.

Figure 5.10 Disassembly window

The columns listed below are to the left of the Disassembly column.

(1) Event column

This column shows the following:

Table 5.4 Icons in the Event column

Hardware breakpoint

Trace point (fetch condition)

A hardware breakpoint can be set by double-clicking in the Event column.

A trace point is only displayed when a fetch condition has been set.
