/** \file rom400_init.h
 *  \brief ROM Initialization functions in the DS80C400 ROM
 *
 *  This library contains functions for initializing the functionality
 *  in the ROM.  Note that the preferred way of initializing the ROM is
 *  to simply call the <i>#init_rom</i> function.  However, you can also
 *  initialize the various modules individually.  To do this, call 
 *  these functions in this order:
 *     -# <i> #init_clearXSEG </i>
 *     -# <i> #init_copyivt </i>
 *     -# <i> #init_redirect </i>
 *     -# <i> #init_clearSystemRAM </i>
 *     -# <i> #init_mm </i>
 *     -# <i> #init_km </i>
 *     -# <i> #init_ow </i>
 *     -# <i> #init_network </i>
 *     -# <i> #init_eth </i>
 *     -# <i> #init_sockets </i>
 *     -# <i> #init_tick </i>
 *     -# <i> #task_genesis </i> [in the process scheduler library]
 *     -# <i> #init_enableinterrupts </i>
 *
 *  For detailed information on the DS80C400 please see the
 *  <a href="http://pdfserv.maxim-ic.com/arpdf/Design/DS80C400UG.pdf">
 *  High-Speed Microcontroller User's Guide: DS80C400 Supplement</a>.
 *
 *  Functions in this library should only be called once on startup.
 *  The safety of calling these functions from multiple processes at
 *  the same time is irrelevant.

 * Initializes the network stack, memory manager, process scheduler, and 
 * other modules in the DS80C400 Silicon Software.  Calling this method is
 * the preferred way of initializing the ROM.
 *
 * Note that calling this function will cause the ROM to copy its own
 * interrupt table into memory.  If you have any interrupts installed
 * before calling this function (for instance, you use the Keil compilers
 * <i>interrupt</i> keyword to declare your function an interrupt handler), 
 * the entry in the interrupt table will be erased.
 *
 * <i>init_rom</i> prints status information to the serial port if serial 0
 * is set to use timer 2. If that is not desired, clear <i>tr2</i>.
 * <code>
 *   #include "reg400.h"
 *   ...
 *   TR2 = 0;
 *   init_rom(...);
 *   TR2 = 1;
