To prevent lock-up caused by use case #2 a timeout for the SVSMLDLYIFG flag check
should be implemented to 300us.

Functional
Function In-system debugging causes the PMALOCKED bit to be always set
Description The port mapping controller registers cannot be modified when single-stepping or halting
at break points between a valid password write to the PMAPWD register and the expected
lock of the port mapping (PMAP) registers. This causes the PMAPLOCKED bit to remain
set and not clear as expected.
Note: This erratum only applies to in-system debugging and is not applicable when
operating in free-running mode.
Workaround Do not single step through or place break points in the port mapping configuration section
of code.
PORT19
PORT Module
Category
Functional
Function Port interrupt may be missed on entry to LPMx.5
Description If a port interrupt occurs within a small timing window (~1MCLK cycle) of the device entry
into LPM3.5 or LPM4.5, it is possible that the interrupt is lost. Hence this interrupt will not
trigger a wakeup from LPMx.5.
Workaround None
SD3
SD Module

Functional
Function Incorrect conversion result in twos complement mode when -VFS is applied
Description When the SD converter is configured in twos complement mode with left or right
alignment and any OSR setting, applying the -VFS voltage at the input will result in an
erroneous output.
Workaround None.
UCS11
UCS Module
Category
Functional
Function Modifying UCSCTL4 clock control register triggers an additional erroneous clock request
Description Changing the SELM/SELS/SELA bits in the UCSCTL4 register will correctly configure the
respective clock to use the intended clock source but might also erroneously set XT1/XT2
fault flag if the crystals are not present at XT1/XT2 or not configured in the application
firmware. If the NMI interrupt for the OFIFG is enabled, an unintentional NMI interrupt will
be triggered and needs to be handled.
