This figure reflects the C-SPY simulator.

Use the Code breakpoints dialog box to set a code breakpoint, see Setting breakpoints using the dialog box.

Break At

Specify the code location of the breakpoint in the text box. Alternatively, click the Edit button to open the Enter Location dialog box, see Enter Location dialog box.

Size

Determines whether there should be a size—in practice, a range—of locations where the breakpoint will trigger. Each fetch access to the specified memory range will trigger the breakpoint. Select how to specify the size:

Auto

The size will be set automatically, typically to 1.

Manual

Specify the size of the breakpoint range in the text box.

Note

This option might not be supported by the combination of C-SPY driver and device that you are using.

Action

Specify a valid C-SPY expression, which is evaluated when the breakpoint is triggered and the condition is true. For more information, see Useful breakpoint hints.

Conditions

Specify simple or complex conditions:

Expression

Specify a valid C-SPY expression, see C-SPY expressions.

Condition true

The breakpoint is triggered if the value of the expression is true.

Condition changed

The breakpoint is triggered if the value of the expression has changed since it was last evaluated.

Skip count

The number of times that the breakpoint condition must be fulfilled before the breakpoint starts triggering. After that, the breakpoint will trigger every time the condition is fulfilled.
