Forum Post: RE: What effects does debug under CCSv5 with SBW connections have on interrupt response?

[quote user="Doug Lochner"]Regardless, I'd be interested in an app note or some-such that indicates how the debug tool (MSP-FET430UIF) and SBW and JTAG each interact with the processor.[/quote]The introduction to Advanced Debugging Using the Enhanced Emulation Module (EEM) With Code Composer Studio Version 6 SLAA393E claims: [quote]The EEM logic in the MSP430 works nonintrusively, meaning that it does not use or lock any resources targeted for the application, such as registers, memory, or interrupts.[/quote]Which is at odds with your observed behavior. When you run the program under the debugger are there any breakpoints, watchpoints or EEM trace active? Also, do you have any indication of how often the UART corruption occurs? Wondering if you can try and see if the rate of UART corruption ties in with how often the MSP-FET430UIF is access the target device over the SBW connection.
