// Program Description:
//
// Register/bit definitions for the C8051F30x family.
// **Important Note**: The compiler_defs.h header file should be included
// before including this header file.
//
// Target:         C8051F300, 'F301, 'F302, 'F303, 'F304, 'F305
// Tool chain:     Generic
// Command Line:   None
//
// Release 1.3 - 07 AUG 2007 (PKC)
//    -Removed #include <compiler_defs.h>. The C source file should include it.
//    -Removed FID and fixed formatting.
// Release 1.2 - 15 NOV 2006 (PKC/BW)
//    -Reformatted header file to enable portable SFR definitions
// Release 1.1 - 11 JAN 2006 (GP)
//    -Converted file to new coding guidelines
//    -Added #defines for interrupt priorities
//    -Added #ifndef/#define to allow multiple includes of file
// Release 1.0
//    -Latest release before new firmware coding standard
