To clear all execution breakpoints

•

When displaying breakpoints, position the mouse pointer within the breakpoints
display screen, press and hold the select mouse button, and choose Clear (delete)
All Breakpoints from the popup menu.

•

Choose Breakpoints

→

Clear All.

•

Using the command line, enter:

To display the status of all execution breakpoints

•

Choose Breakpoints

Breakpoints.

•

Using the command line, display the status of all breakpoints by selecting:

display software_breakpoints

The breakpoints table shows you whether the breakpoints feature is currently
enabled or disabled. Also, the status is shown for each breakpoint in memory. If
“Pending,” the BKPT instruction is in memory at that location and the breakpoint is
set. If “Inactive,” the memory location contains the original instruction, and the
breakpoint will not be executed.

Active breakpoints are indicated in the memory mnemonic display by asterisks
beside the lines with breakpoints set.

The status of a breakpoint can be:

temporary

Which means the temporary breakpoint has been set but
not encountered during program execution. These
