56 // This header file defines configurations, registers, and other useful bits of
57 // information for the PIC16C621 microcontroller. These names are taken to match
58 // the data sheets as closely as possible.
60 // Note that the processor must be selected before this file is
61 // included. The processor may be selected the following ways:
63 // 1. Command line switch:
64 // C:\ MPASM MYFILE.ASM /PIC16C621
65 // 2. LIST directive in the source file
67 // 3. Processor Type entry in the MPASM full-screen interface
