;
;  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 /PIC16C57
;       2. LIST directive in the source file
;               LIST   P=PIC16C57
;       3. Processor Type entry in the MPASM full-screen interface
;       4. Setting the processor in the MPLAB Project Dialog
