EEM Module

Function

Switching off FRAM LDO stalls device during debug access

Description

With the "Enable Ultra Low Power debug/LPMx.5 debug" option disabled in the IDE, if user application switches off the FRAM LDO (FRPWR = 0) and a debug halt is requested during this time, device debug control is lost and the debug session must be restarted. At this point, the code execution is also stalled.

The following error message is observed:
IAR - "Internal error: (State)"
CCS - "MSP430: Trouble Halting Target CPU: Internal error"

Workaround

If IDE error message is observed, restart the debug session or perform a hardware reset. Turn on "Enable Ultra Low Power debug/LPMx.5 debug" option in the IDE debug settings.
