I locked myself out while changing to external Clock. How to repair?

Hi there to everyone.

I have a ADuC7126 Evaluation Board, uvision3,  Realview-compiler and want to evaluate a  Signal Generator.

As i found the 41.7792 MHz PLL has a strong jitter, i thought it would be a good idea to supply the ADuC7126 with an external 40MHz XTAL-Clock on P0.7

So i found i had locked myself out, it is not possible to Download Flash anymore.

Probably my code was to stupid, i need an example-code how to switch to external clock source.

The code in the datasheet is not complete.

 

Everytime i want to download Flash or entering the debugger the error-message appears "Cannot stop Arm device"

Can this be repaired without replacing the ADuC7126 with a soldering iron?
