External Memory Usage
5.5
MPLAB IDE AND EXTERNAL MEMORY
Using External Memory modes with MPLAB ICE 4000 will impact the following features
of MPLAB IDE.
5.5.1
Viewing Program Memory
To view the program memory, select View>Program Memory . The data for emulator
program memory is always displayed. The data for external (target board) memory will
be displayed as long as “Use External Memory” has been specified in the External
Memory dialog ( Configure>External Memory ). To refresh the external memory display,
select Debugger>Upload Program Memory from ICE after you run, single step or trace.
If uploading takes too long, you may wish to change the amount of external memory
used in the External Memory dialog.
5.5.2
Stepping Through Code
If your external Flash memory contains code that is written in a high-level language,
such as C, you cannot step through this code using the File (Editor) window. You must
use the Program Memory window.
5.5.3
Setting Breakpoints
Software breakpoints may be set for emulator memory or external RAM memory.
Hardware breakpoints, set using the complex trigger, may be used for either emulator
or any type of external memory.
