I was using the "Measure" program as the basis for an application. The target device was selected to be a P89LPC935 (I needed the A/D). Everything works fine in simulation with one annoying exception: The debug options "Load application at startup" and "Run til main()" are set. Every time I activate debug I get the error: ***error 65: Access violation at c:0x1E00 : no 'execute/read' permission**** The program counter is set to 0x1E00 although my application does not use this address (the last used location is 0x1B63). Also, if I use the "Processor Reset" function, the PC resets to a value of 0x1E00. I have overecome the problem by writing an ini file that contains the statement PC = 0x0000, but why is this hapenning?
