DFlash writing MPC560D40

Hello,

 

How is it possible to  write 64 bit in the DFLASH with one High Voltage operation?

I try like this:

   PGM = 1

   (0x00800000) = 0x1122334455667788;

   EHV = 1

 

   wait for DONE

   EHV = 0

   PGM = 0

 

The result is:

0x00800000 = 0xFFFFFFFF;

0x00800004 = 0x11223344;

 

What am I doing wrong?

 

I know that on the 5604 the writing was possible and since it is the same architecture it should be pretty straight forward. Also, the datasheet specifies it is possible (check attachment).

 

Thank you for your support.
