QUESTION

Is it possible for me to use the Monitor to debug my program stored in Flash memory?

ANSWER

No it isn't. In order to use the Monitor, your program must be stored in writeable, executable memory. The reason is the Monitor needs to treat your code as data in order to implement such things as breakpoints.

With the 8051, you can turn your RAM into executable memory by combining the /WR /RD and /PSEN signals appropriately into a chip select signal.
