Basic Features
5.8.2 Named Software Break Points
MPLAB allows up to 16 named software break point ranges to be specified.
These break points can then be selectively enabled and disabled. Break
points set in this manner are retained with the project.
Select Debug>Break Settings to display the Break Point Settings dialog.
5.9 Using Hardware Break Points
In addition to setting software break points on program memory addresses,
hardware break points may be set with more complex conditions. Also,
hardware break points can be used to capture real-time events.
With a hardware break point, execution halt may skid, or one or more
additional instructions may be executed past the set break point before the
processor halts.
5.9.1 Right Mouse Button Hardware Break Points
A simple complex trigger break point can be set by using the right mouse
button. In a source window, a listing window, or the program memory window,
select the desired lines by clicking and dragging. Then select Complex
Trigger Break Point(s) on the right mouse button menu.
Figure 5.2: Right Mouse Button Menu - Complex Trigger
This will set up and apply a single event sequential trigger with Ignore FNOP
Cycles and Halt on Trigger set.
Addresses can be removed from the specification by repeating the process. If
a complex trigger is already specified and it conflicts with the break point
specification, you will be asked to verify the operation.
Note: Break points set in this manner are lost when the project is rebuilt
or closed.
