ULP debug support enables users to debug in the low-power modes that are used in their application software.
If this option is enabled during an active debug session in IAR EW430 or Code Composer studio, the target MSP430 MCU enters the low-power modes. Wake-up times can be measured on F5xx, F6xx, FR5xx, and FR6xx devices. For some MSP430 MCUs, special debug features are disabled in this mode; for example, setting breakpoints (hardware and software) while device is running in ULP mode.
NOTE
When debugging with EnergyTrace++ active, this mode must be used.
NOTE
Measured currents might be slightly higher than in stand-alone mode (EnergyTrace) due to the active debugger connection.
For more details and information, see the MSP430 Ultra-Low-Power LPMx.5 Mode section of the IAR Embedded Workbench IDE for MSP430 user's guide and Code Composer Studio IDE for MSP430 user's guide.
