 * MPLAB-C30  dsPIC30F6012A processor header
 *
 * (c) Copyright 2005 Microchip Technology, All rights reserved
 *
 * File Description / Notes:
 * =========================
 * 1] This header file defines special function registers (SFR), and useful  
 *    macros for the dsPIC30Fxxxx Family of Digital Signal
 *    Controllers (also referred to as the dsPIC).  
 * 2] The register and bit names used in this file match the  
 *    dsPIC30Fxxxx data sheets as closely as possible.  
 * 3] The memory locations of the registers defined in this header file are
 *    specified in the respective linker scripts.
 * 4] SFR definitions are listed in the ascending order of memory addresses
 *    and are grouped based on the module they belong to. For e.g., WREG10
 *    is listed before ACCAL, and the Core SFRs are grouped separately
 *    from the Interrupt Controller SFRs or the General Purpose Timer SFRs.
 *
