? To perform a processor reset on your code, select either Debugger>Reset>
Processor Reset or Reset from the Debug toolbar. Additional resets, such as
POR/BOR, MCLR and System, may be available, depending on device.
Remember to rebuild your program when making changes so the code being executed
accurately reflects the current state of your application.

VIEWING PROCESSOR MEMORY AND FILES
MPLAB IDE provides several standard windows for viewing debug and various
processor memory information, selectable from the View menu. See MPLAB IDE
on-line help for more information on using these windows.

Project – view the project tree
Output – view output from build and other tools
Hardware Stack – view the hardware stack contents
Program Memory – view program memory contents
File Registers – view file register contents
EEPROM – view the EEPROM memory contents
Watch – view selected SFRs and symbols
Special Function Registers – view SFR contents
In addition, you may view trace results. For more on trace, see Chapter 7. “Code
? ICE Trace – view the contents of the trace buffer
To view your source code, select File>Open and enter or browse for the source code
file. Code in this window is color-coded according to the processor and build tool
selected. To change the style of color-coding, click the right mouse button and select
Advanced>Text Mode . To change the colors used, click the right mouse button and
select Properties, Text tab. For information on using this window to edit your code, see
MPLAB Editor on-line help.

USING SOFTWARE BREAKPOINTS
MPLAB ICE 4000 uses software breakpoints to halt the processor at a specific location.
With a software breakpoint, execution stops before the instruction at the break location
is executed.
Note:
You cannot set software breakpoints in external Flash memory. Use the
complex trigger to set hardware breakpoints.
You can set software breakpoints in external RAM memory.
Some considerations when using software breakpoints:
? If a software breakpoint is set, then checksums calculated on program memory at
run time will be incorrect. Programmer checksums are not affected.
? Manually resetting the time-stamp when using software breakpoints will cause the
time-stamp to be incorrect.
Software breakpoints are a standard MPLAB IDE debug feature:
