FILE : startcf.h
|
|
PURPOSE : startup code for ColdFire
|
|
LANGUAGE: C
|
|
|
|
|
|
Notes:
|
|
1) Default entry point is _startup.
|
|
. disable interrupts
|
|
. the SP is set to __SP_AFTER_RESET
|
|
. SP must be initialized to valid memory
|
|
in case the memory it points to is not valid using MEMORY_INIT macro
|
|
2) __initialize_hardware is called. Here you can initialize memory and some peripherics
|
|
at this point global variables are not initialized yet
|
|
3) After __initialize_hardware memory is setup; initialize SP to _SP_INIT and perform
|
|
needed initialisations for the language (clear memory, data rom copy).
|
|
4) void __initialize_system(void); is called
|
|
to allow additional hardware initialization (UART, GPIOs, etc...)
|
|
5) Jump to main
|
