LPMx.5 debug limitations
Debugging the device in LPMx.5 mode might wake the device up from LPMx.5 mode inadvertently, and it is possible that the device enters a lock-up condition; that is, the device cannot be accessed by the debugger any more.
Follow the debugging steps in Debugging MSP430 LPM4.5 SLAA424 .
