CCS/MSP430FR2433: Debugger always stops on __enable_interrupt() and __disable_interrupt()

Stuart Baker

Part Number: MSP430FR2433

Tool/software: Code Composer Studio

I'm encountering a strange issue that I can't explain. I have no breakpoints set in my program, however, the debugger is always stopping on every call to __enable_interrupt() and __disable_interrupt(). If I dig into the disassembly view, I see that it the PC is stopped on the nop instruction (Op code 0x4303) directly following the DINT or EINT instruction.

Has anyone seen anything like this before? I'm at a loss for what is happening. I've scrutinized my debug settings and tried two different versions of code composer studio (8.0.0 and 8.2.0), both of which exhibit the issue.

TI emulation pack version 8.0.903.6.

Thanks,

Stuart
