/*
 *  PAGE 0 will be used to organize program sections
 *  PAGE 1 will be used to organize data sections
 *
 *  Notes:
 *        Memory blocks on F2802x are uniform (ie same
 *        physical memory) in both PAGE 0 and PAGE 1.
 *        That is the same memory region should not be
 *        defined for both PAGE 0 and PAGE 1.
 *        Doing so will result in corruption of program
 *        and/or data.
 *
 *        L0 memory blocks are mirrored - that is
 *        they can be accessed in high memory or low memory.
 *        For simplicity only one instance is used in this
 *        linker file.
