Wisp628, yes good. Programming data eeprom with wisp628 - no I haven't tried
this.

Look at the hex file you are trying to program into the PIC, locate the records
at 2100 and compare this with what gets programmed into the pic. Do you see any
patern like maybe bytes swapped or any other data in the hex file you are not
expecting?
