; P16C5XD.INC  Defines Header File, Version 2.01     Microchip Technology, Inc.
	NOLIST

; This header file defines short cuts for register bits for the 16C5X 
; microcontrollers.  This is an optional file for users and may not
; be fully supported by Microchip. The user however, can modify 
; and utilize this file as required.
; The microcontrollers included in this file are:

;    16C54
;    16C54A
;    16C55
;    16C56
;    16C57
;    16C58A

; There is one group of defines that is valid for all microcontrollers.  
; Each microcontroller in this family also has its own section of special 
; defines.  Note that the processor must be selected and the file P16C5X.INC
; included before this file is included.  The processor may be selected the 
; following ways:

;       1. Command line switch:
;               C:\ MPASM MYFILE.ASM /P16C54A
;       2. LIST directive in the source file
;               LIST   P=16C54A
;       3. Processor Type entry in the MPASM full-screen interface
