 The following  software  is for  demonstration  purposes only.  It is not
 fully  tested, nor validated  in order  to fullfill  its task  under  all
 circumstances.  Therefore,  this software or  any part of it must only be
 used in an evaluation laboratory environment.                        
 This software is subject to the rules of our standard DISCLAIMER, that is
 delivered with our  SW-tools on the Fujitsu Microcontrollers CD

==========================================================================

- This sample uses an Analog - Digital conversion and UART0 
	
	The AD converter catches a digital value from  signal on Pin 37 (AN1).
	The value from the AD converter is shown on Port 0 (LED磗).
	With the value a subroutine calculates the impressed voltage on Pin 37 (AN1)
	and sends it to the terminal. 
      

NOTE1:
-----
NO SECURITY IS USED IN THIS EXAMPLE. TAKE CARE, SPECIFY CORRECT SECURITY 
ADDRESS ACCORDING TO USED SERIES.
Refer to Note 3.

NOTE2:                                                                        
------                                                                            
The header-file will cover all features of the Emulation chip MB90V340/S.   
No Flash- or Mask- version of the MB90340series will support all features!
Limitaions can be found in 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 MB90340series.    

NOTE 3:    
-------
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.
