Am working with the ST10F276 and I'm trying to write to the XFlash memory.
When I try to access one of the flash registers (FCR0H, FARL, ...) the microcontroller stops working.
My code (Keil):
FCR0H = (unsigned int huge*)(0x000E0002);
*FCR0H =0x2000;
Does anybody know why this problem occurs?

Well, i´m not sure about this...
If you haven´t solved the problem yet, try indirect addressing to Flash Control Registers. Direct addressing mode (FCR0H = 0x2000) is not allowed to Flash Control Registers.
Try:
FCR0H |= 0x2000 for the WPG Bit
You can also try to read out the Flash Error register FER. Bit SEQUER should be set if this was your problem.
