Function
DMA may corrupt data in debug mode
Description
When the DMA is enabled and the device is in debug mode, the data written by the DMA
may be corrupted when a breakpoint is hit or when the debug session is halted.
Workaround
This erratum has been addressed in MSPDebugStack version 3.5.0.1. It is also available
in released IDE EW430 IAR version 6.30.3 and CCS version 6.1.1 or newer.
If using an earlier version of either IDE or MSPDebugStack, do not halt or use breakpoints
during a DMA transfer.
Note
This erratum applies to debug mode only.

Function
EEM triggers incorrectly when modules using wait states are enabled
Description
When modules using wait states (USB, MPY, CRC and FRAM controller in manual mode)
are enabled, the EEM may trigger incorrectly. This can lead to an incorrect profile counter
value or cause issues with the EEMs data watch point, state storage, and breakpoint
functionality.
Workaround
None.
Note
This erratum affects debug mode only.

LPMx.5 Debug Support Limitations
Description
The JTAG connection to the device might fail at device-dependent low or high supply
voltage levels if the LPMx.5 debug support feature is enabled. To avoid a potentially
unreliable debug session or general issues with JTAG device connectivity and the
resulting bad customer experience Texas Instruments has chosen to remove the LPMx.5
debug support feature from common MSP430 IDEs including TIs Code Composer Studio
6.1.0 with msp430.emu updated to version 6.1.0.7 and IARs Embedded Workbench
6.30.2, which are based on the MSP430 debug stack MSP430.DLL 3.5.0.1
TI plans to re-introduce this feature in limited capacity in a future release of the debug
stack by providing an IDE override option for customers to selectively re-activate LPMx.5
debug support if needed. Note that the limitations and supply voltage dependencies
outlined in this erratum will continue to apply.
For additional information on how the LPMx.5 debug support is handled within the
MSP430 IDEs including possible workarounds on how to debug applications using
LPMx.5 without toolchain support refer to
