The Data Log breakpoints dialog box is available from the context menu in the editor window, Breakpoints window, the Memory window, and in the Disassembly window.

This description reflects the C-SPY hardware debugger drivers. For the C-SPY Simulator, see Data Log breakpoints dialog box.

Use the Data Log breakpoints dialog box to set a maximum of four data log breakpoints.

You can set a data log breakpoint on 8, 16, and 32-bit variables.

Requirements

A device and a debug probe that either supports ITM and SWO, or supports delivering ETM and ITM trace concurrently.

Trigger at

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

Access Type

Selects the type of memory access that triggers the breakpoint:

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:

Trigger range

Shows the requested range and the effective range to be covered by the trace. The range suggested is either within or exactly the area specified by the Trigger at and the Size options.
