Files List

• 5131_drv.h
  
This file contains the C51 driver definition
• compiler.h
  
This file redefines dedicated KEIL, RAISONANCE and TASKINKG C51/C251 keywords in order to ensure that any source file can be processed by these compilers.
• ext_5131.h
  
It defines mask for registers. ---------------------------------------------------------------------------- CHANGES:
• reg_5131.h
  
This file defines Sfr registers and BIT Registers for AT89C5131 (Keil notation is the reference)
