MPLAB ? REAL ICE ? In-Circuit Emulator User’s Guide
? The target device must have its configuration words programmed correctly:
- The oscillator Configuration bits should correspond to RC, XT, etc., depending
upon the target design.
- For some devices, the Watchdog Timer is enabled by default and needs to be
disabled.
- The target device must not have code protection enabled.
- The target device must not have table read protection enabled.
Once the above conditions are met, you may proceed to the following:

Sequence of Operations Leading to Debug Mode
Given that the Requirements For Debug Mode are met, these actions can be
performed when the MPLAB REAL ICE in-circuit emulator is set as the current
debugger ( Debugger>Select Tool ):
? When Debugger>Program is selected, the application code is programmed into
the device’s memory via the ICSP protocol as described above.
? A small “debug executive” program is loaded into the high area of program
memory of the target device. Since the debug executive must reside in program
memory, the application program must not use this reserved space. The debug
executive typically needs about 0x120 words of program memory. Some devices
have special memory areas dedicated to the debug executive. Check your device
data sheet for details.
? Special “in-circuit debug” registers in the target device are enabled. These allow
the debug executive to be activated by the emulator.
? The target device is held in Reset by keeping the V PP /MCLR line low.
