Use the Software Code Breakpoint dialog box to set a software code breakpoint.

Note

Because the memory must be reprogrammed after a software code breakpoint has been triggered, software code breakpoints should if possible be used only in RAM memory or for breakpoints that are not triggered so often.

Requirements

A C-SPY hardware debugger driver.

Break At

Specify the 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.

Action

Determines whether there is an action connected to the breakpoint. Specify an expression, for instance a C-SPY macro function, which is evaluated when the breakpoint is triggered and the condition is true.

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.
