; P16C557.INC  Standard Header File, Version 1.00    Microchip Technology, Inc.
        NOLIST

; This header file defines configurations, registers, and other useful bits of
; information for the PIC16C557 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 /p=16C557
;       2. LIST directive in the source file
;               LIST   P=16C557
;       3. Processor Type entry in the MPASM full-screen interface
