-;=========================================================================================
-;
-#set BOOT_FLASH_SEC OFF ; <<< BOOT and Flash Security Vector
-;
-; The flash devices have two flash and two boot security vectors. It is important to set
-; the four vectors correctly. Otherwise it might be possible, that the flash device is
-; not accessible any more via the bootrom. Please read carefully the hardware manual.
-;
-; OFF: The security feature is switch off. The section SECURITY_VECTORS is reserved and
-; the vectors are set.
-; ON: IMPORTANT! The security vectors are not set. But the section SECURITY_VECTORS
-; is reserved.

;
-#set STACK_FILL OFF ; <<< fills the stack area with pattern
-#set STACK_PATTERN 0x55AA6699 ; <<< the pattern to write to stack
-;
; - If the active stack is set to SYSSTACK, it is used for main program and interrupts.
; In this case, the user stack could be set to a dummy size. If the active stack is
; set to user stack, it is used for the main program but the system stack is
; Check the stack information files (*.stk) in the LIB\911 directory.

-;=========================================================================================
-;
-#set I_RAM ON ; <<< select if code in section IRAM

-;
-; If this option is activated code located in the section IRAM is copied during startup
-; from ROM to the instruction-RAM. The code is linked for the instruction-RAM.

-;=========================================================================================
-; 4.5 Low-Level Library Interface
-;=========================================================================================
-;
-#set CLIBINIT OFF ; <<< select ext. libray usage
-;
-; This option has only to be set, if stream-IO/standard-IO function of the C-libraray
-; have to be used (printf(), fopen()...). This also requires low-level functions to be
-; defined by the application software.
-; For other library functions like (e.g. sprintf()) all this is not necessary. However,
-; several functions consume a large amount of stack.
-;
-;=========================================================================================
-; 4.6 C++ start-up
-;=========================================================================================
-;
-#set CPLUSPLUS OFF ; <<< activate if c++ files are used
-;
-; In the C++ specifications, when external or static objects are used, a constructor
-; must be called followed by the main function. Because four-byte pointers to the main
-; function are stored in the EXT_CTOR_DTOR section, call a constructor sequentially from
-; the lower address of the four addresses in that section. If using C++ sources,
-; activate this function to create the section EXT_CTOR_DTOR.

; ; <<< Select clock configuration
;
-; There are different default configurations available, where all necessary settings for
-; clocks and the related registers are made. Beside this configurations, there is the
-; possibility to define a user configuration in the chapter "Definition of
-; Configurations"
-;
-; - NO_CLOCK means:
-; The clock registers are not set by the start-up file.
-;
-; - PLL_4MHZ__CPU__64MHZ_PER_16MHZ_EXT_32MHZ_CAN_16MHZ means:
-; Main oszillation = 4 MHz, PLL is activated
-; CPU clock (CLKB) = 64 MHZ
-; Peripheral clock (CLKP) = 16 MHZ
-; Ext. bus clock (CLKT) = 32 MHZ
-; CAN clock (CLKCAN) = 16 MHz, using PLLx
-;
-; - CLOCK_USER:
-; The user configuration definded in the chapter "Definition of Configurations" is set.
-;

-; 4.8 External Bus Interface
-;
-; The rest of the configuration is only applicable for devices with an external bus
-; interface.
-;
-; If the device does not offer an external bus interface, the configuration can be
-; stoped at this point.
-;
-;=========================================================================================
-;
-#set EXTBUS DEFAULT ; <<< Ext. Bus on/off
-;
-; ON - The ext. bus interface is enabled and is configured as
-; set below.
-;
-; OFF - The ext. bus interface is diabled. The port function
-; registers are set to general I/O. The registers of
-; ext. bus interface will not be touched by the start-up
-; file.
-; Be aware, that the device might be conifgured in ext.
-; bus mode by default after reset.
-;
-; DEFAULT - Neither the register nor the respective port function
-; registers are touched by the start-up file.
-; Be aware, that the device might be conifgured in ext.
-; bus mode by default after reset.
-;
-;
-; Note: This feature is not supported by every device. Please check the data sheet. The
-; following devices for example do not offer an external bus interface: MB91464A,

-; The bit meaning depends on the configured bus interface type. The bus interface can be
-; configured for different memory types. Depending on the memory type, the wait register
-; bits have a differnt meaning. CS0-5 should be configurable as ordinary bus interface
-; (w/o SDRAM and FRAM) and CS6-7 should be configurable as SDRAM and FRAM. It is also
-; possible and for some devices neccessary to configure other two chip selects as SDRAM
-; or FRAM interface. In such a case be aware of the bit meanings.
