52 // This header file defines configurations, registers, and other useful bits of
53 // information for the PIC16C554 microcontroller. These names are taken to match
54 // the data sheets as closely as possible.
56 // Note that the processor must be selected before this file is
57 // included. The processor may be selected the following ways:
59 // 1. Command line switch:
60 // C:\ MPASM MYFILE.ASM /PIC16C554
61 // 2. LIST directive in the source file
63 // 3. Processor Type entry in the MPASM full-screen interface
