Running HEX files from the PICDEM 17
Demonstration Board
The Monitor program has a Run button that starts the execution of code from
the external FLASH program memory. Once a program has been downloaded
into the FLASH memory, click the Run button to start execution. Control of the
PIC17C756A is released by the Monitor firmware by simply writing 4000h to
the PCLATH:PCL registers. Refer to Chapter 4, Using the MPLAB
for more information.

The only way to stop the program from running is to click on the Reset button
in the Monitor window. This resets the PIC17C756A and restores operation to
the Monitor firmware. This method allows for all Data memory, interrupt
vectors, and stack locations to be available to the user for the target
application.
