Hello (Daniel), In reply to our email.
Problem description: The processor (msp430f1122) is programmed using it's JTAG pins. After the programming is done, I like to test some basic functions (All the IO pins are used). To place the processor in another (e.g. debug) mode, the programmer writes at RAM location 0x200 a specific value (using the JTAG pins). In the main loop of the program I only have to check the address 0x200 and then go into debug mode. I am sure this is not the only/best way to do this, but I have already several other devices that work this way (These were made with the IAR toolsuite). I do not want to change the programmer.
