• Enable/disable a selected control point by checking or unchecking the related
checkbox.
• Enable/disable multiple control points by checking or unchecking the related
checkbox.
• Enter or modify the condition of a selected control point.
• Enable/disable the condition of a selected control point by checking/unchecking the
related checkbox.
• Enter or modify the command of a selected control point.
• Enable/disable the command of a selected control point by checking/unchecking the
related checkbox.
• Enable/disable multiple control point commands by selecting control points and
checking/unchecking the related checkbox.
• Modify the counter and/or limit of a single control point.
With breakpoints, the following operations are also available:
• Enable/disable halting on a single temporary breakpoint by checking/unchecking the
matching checkbox.
• Enable/disable halting on multiple temporary breakpoints by checking/unchecking
the matching checkbox.
With watchpoints, the following operations are also available:
• Enable/disable halting on a single read and/or write access by checking/unchecking
the corresponding checkboxes.
• Enable/disable halting on multiple read and/or write accesses by checking/
unchecking the corresponding checkboxes.
• Define the memory range controlled by the watchpoint.
Breakpoints
Breakpoints are control points associated with a PC value. That is, program execution is
stopped as soon as the PC reaches the value defined in a breakpoint. The debugger
supports four different types of breakpoints:
• Temporary breakpoints, which are activated next time the instruction is executed.
• Permanent breakpoints, which are activated each time the instruction is executed.
• Counting breakpoints, which are activated after the instruction has been executed a
certain number of times.
• Conditional breakpoints, which are activated when a given condition is TRUE.
