  FILE    : startcf.h
3
  PURPOSE : startup code for ColdFire
4
  LANGUAGE: C

  Notes:
8
        1) Default entry point is _startup.
9
           . disable interrupts
10
           . the SP is set to __SP_AFTER_RESET
11
           . SP must be initialized to valid memory
12
             in case the memory it points to is not valid using MEMORY_INIT macro
13
        2) __initialize_hardware is called. Here you can initialize memory and some peripherics
14
           at this point global variables are not initialized yet
15
        3) After __initialize_hardware memory is setup; initialize SP to _SP_INIT and perform
16
           needed initialisations for the language (clear memory, data rom copy).
17
        4) void __initialize_system(void); is called
18
           to allow additional hardware initialization (UART, GPIOs, etc...)
19
        5) Jump to main
