Breakpoint Usage window
The Breakpoint Usage window is available from the menu specific to the C-SPY driver you are using.

This window lists all breakpoints currently set in the target system, both the ones you have defined and the ones used internally by C-SPY. The format of the items in this window depends on the C-SPY driver you are using.
The window gives a low-level view of all breakpoints, related but not identical to the list of breakpoints displayed in the Breakpoints window.
C-SPY uses breakpoints when stepping. Use the Breakpoint Usage window for:
Identifying all breakpoint consumers
Checking that the number of active breakpoints is supported by the target system
Configuring the debugger to use the available breakpoints in a better way, if possible.
For more information, see Breakpoints in the C-SPY hardware debugger drivers.
