@subsection Xstormy16 Variable Attributes
One attribute is currently defined for xstormy16 configurations:
@code{below100}
@table @code
@item below100
@cindex @code{below100} attribute
If a variable has the @code{below100} attribute (@code{BELOW100} is
allowed also), GCC will place the variable in the first 0x100 bytes of
memory and use special opcodes to access it. Such variables will be
placed in either the @code{.bss_below100} section or the
@code{.data_below100} section.
