 *
 * STARTUP_FROM_RESET
 *
 *   If defined, the program will startup from power-on/reset. If not defined
 *   the program will just loop endlessly from power-on/reset.
 *
 *   This definition is not defined by default on this target because the
 *   debugger is unable to reset this target and maintain control of it over the
 *   JTAG interface. The advantage of doing this is that it allows the debugger
 *   to reset the CPU and run programs from a known reset CPU state on each run.
 *   It also acts as a safety net if you accidently download a program in FLASH
 *   that crashes and prevents the debugger from taking control over JTAG
 *   rendering the target unusable over JTAG. The obvious disadvantage of doing
 *   this is that your application will not startup without the debugger.
 *
 *   We advise that on this target you keep STARTUP_FROM_RESET undefined whilst
 *   you are developing and only define STARTUP_FROM_RESET when development is
 *   complete.
