This is a project template for the MB90350 Series. It includes some basic 
settings for e.g. Linker, C-Compiler which must be checked and modified in 
detail, corresponding to the user application.

NOTE1:                                                                        
------                                                                            
The header-file will cover more features than available in the MB90350 Series.   
No Flash- or Mask- version of the MB90350 Series will support all features!
Limitaions can be found in FLASH, UARTs, CANs, I2C, ADC, DAC, etc.                       
Please DO NOT USE resources / registers others than specified                
for the dedicated Flash-/Mask-version.                                       
Please refer to the datasheet and hardwaremanual of the MB90350 Series.    

NOTE 2:    
-------
Security-Feature means that the contents of the (Flash-)ROM
can be prevent from (unauthorized) read-out.
Devices of microcontroller-families with Security-Feature
require three manual definitions within SWB-menu "SetProject->Assembler->DefineMacro" : 

SECURITY_FEATURE 0 => NO  1 => YES  <<< Does the device support the Security-Feature ? 

SECURITY_ADDRESS 0x??0000           <<< Define Security Address
                                        0xFF0000 for  64KB device 
                                        0xFE0000 for 128KB device 
                                        0xFC0000 for 256KB device 
                                        0xF90000 for 384KB device 
                                        0xF80000 for 512KB device 

SECURITY_ENABLE  0 => NO  1 => YES  <<< Enable / Disable Security Feature

The Security-Feature is ENABLED 
if 
    the device supports the Security-Feature generally
and the define SECURITY_FEATURE is set to 1
and the correct SECURITY_ADDRESS is defined
and the Security-mechanism is enabled by SECURITY_ENABLE set to 1

HOW DOES THE SECURITY-FEATURE WORK ? 

In case that a device supports the Security-Feature
the lower two bytes of the (Flash-)ROM are reserved 
for controlling the security mechanism.
If the first two bytes are set 0x01FF, the Security-Feature is enabled. 
If the first two bytes are set 0xFF55, the Security-Feature is disabled
If the Security-Feauture is enabled the (Flash-)ROM can not be read-out anymore. 

If a device does not support the Security-Feature
then set SECURITY_FEATURE 0
The setting for SECURITY_ADDRESS and SECURITY_ENABLE becomes invalid.
