The software now automatically writes a flash loader to the microcontroller, does a blank

check and erases the flash memory if necessary. After that the user application is

programmed to the embedded flash memory.

During this sequence the actual progress status can be seen by checked off steps on the

"Automatic" sheet and the messages below in the message box.

If the programming sequence is ended successfully, you will receive the output shown in

figure 7.

The Addresses 0x14:8000 to 0x14:800F cannot be written in automatic mode. This is a built

in security feature to prevent unintended writing to the Flash Security Vectors and Boot

Security Vectors. Otherwise it would be possible to secure flash content and to lock the

microcontroller for serial programming/reading/erasing by not being able to enter the internal

loader anymore. If you want to use these features explicitly, you have to program these

dedicated addresses by using the "Prog Word" Function of the step-by-step mode.

6.2 Synchronous Mode

In order to program the Flash-ROM synchronously special third-party soft- and hardware has

to be used, e.g. GALEP-4 from www.conitec.de. This tool is not available for free.

A dedicated Flash programming socket (X1) is provided on the evaluation-board for direct

connection to this programmer.
