memory, or the placement should be left to the linker to decide. The
attributes are only significant if compiling for the MSP430X
-architecture.
+architecture in the large memory model.
The attributes work in conjunction with a linker script that has been
augmented to specify where to place sections with a @code{.lower} and
create the application should ensure that persistent data is correctly
placed.
-@item lower
-@itemx upper
+@item upper
@itemx either
-@cindex @code{lower} variable attribute, MSP430
@cindex @code{upper} variable attribute, MSP430
@cindex @code{either} variable attribute, MSP430
These attributes are the same as the MSP430 function attributes of the
same name (@pxref{MSP430 Function Attributes}).
-These attributes can be applied to both functions and variables.
+
+@item lower
+@cindex @code{lower} variable attribute, MSP430
+This option behaves mostly the same as the MSP430 function attribute of the
+same name (@pxref{MSP430 Function Attributes}), but it has some additional
+functionality.
+
+If @option{-mdata-region=}@{@code{upper,either,none}@} has been passed, or
+the @code{section} attribute is applied to a variable, the compiler will
+generate 430X instructions to handle it. This is because the compiler has
+to assume that the variable could get placed in the upper memory region
+(above address 0xFFFF). Marking the variable with the @code{lower} attribute
+informs the compiler that the variable will be placed in lower memory so it
+is safe to use 430 instructions to handle it.
+
+In the case of the @code{section} attribute, the section name given
+will be used, and the @code{.lower} prefix will not be added.
