71 // This header file defines configurations, registers, and other useful bits of
72 // information for the PIC16F84 microcontroller. These names are taken to match
73 // the data sheets as closely as possible.
75 // Note that the processor must be selected before this file is
76 // included. The processor may be selected the following ways:
78 // 1. Command line switch:
79 // C:\ MPASM MYFILE.ASM /PIC16F84A
80 // 2. LIST directive in the source file
82 // 3. Processor Type entry in the MPASM full-screen interface
