Once I got over the fact that the words where in fact 16 bit words of the pc and the address needs to be divided by 2, and not the 14bit words of the PIC, the problems went away (kinda). Also the little endian-ness of the byte ordering is not a problem (now I know it's there) as I can swap or not. So Wouter, does the Wisp628 take the bytes in little or big endian form?
