 Global variables defined in the C code can be read in 16bit mode if
-the variable declaration is marked with VAR16, VAR16_32, VAR16EXPORT,
-or VAR16FIXED.  The GET_GLOBAL macro will then allow read access to
-the variable.  Global variables are stored in the 0xf000 segment, and
-their values are persistent across soft resets.  Because the f-segment
-is marked read-only during run-time, the 16bit code is not permitted
-to change the value of 16bit variables (use of the SET_GLOBAL macro
-from 16bit mode will cause a link error).  Code running in 32bit mode
-can not access variables with VAR16, but can access variables marked
-with VAR16_32, VAR16EXPORT, VAR16FIXED, or with no marking at all.
