Step Over
Debug>Run>Step Over
Step Over functions identically to Step, except when the executed instruction
is a
CALL
. In this case, Step Over executes the called subroutine in real time
and halts at the address following the call.
Execute an Opcode
Debug>Execute>Execute an Opcode
Execute one or more instructions without modifying the program memory.
5.8 Using Software Break Points
MPLAB ICE uses software break points to halt the processor at a specific
location. With a software break point, execution stops before the instruction at
the break location is executed.
5.8.1 Right Mouse Button Software Break Points
A software break point is set by clicking the right mouse button with the cursor
over the desired break location. If a range of breaks is desired, click and drag
the mouse over the desired range. The right click brings up the menu of
Figure 5.1.
Figure 5.1: Right Mouse Button Menu - Software Break Point(s)
Select Software Break Point(s) to set software break point(s). Selecting Run
to Here will set a temporary software break point.
A break point can be set in the source, absolute listing, or program memory
window. The break points are indicated in all of these windows.
Note 1: Break points set in this manner are lost when the project is
rebuilt or closed.
2: Typically, software break points can be set at code execution
addresses in external memory if table writes to external mem-
ory are functional.
3: If you cannot set a software break point, a hardware break point
may be set using the complex trigger.
