// This header file defines configurations, registers, and other useful bits of
// information for the PIC16C433 microcontroller.  These names are taken to match 
// the data sheets as closely as possible.  

// Note that the processor must be selected before this file is 
// included.  The processor may be selected the following ways:

//       1. Command line switch:
//               C:\ MPASM MYFILE.ASM /PIC16C433
//       2. LIST directive in the source file
//               LIST   P=PIC16C433
//       3. Processor Type entry in the MPASM full-screen interface
