Flash burst programming in reverse order

Hello All,


has anyone tried burst programming 9S08 Flash in reverse order, IOW with descending addresses?


I didn't investigate it further but found that programming a certain block works well in reverse order (in my example 32 bytes 0xe220..0xe200) but got strange results in other locations, e.g. shifted and doubled programming.


My algorithm works if I change the command from 0x25 to 0x20.


As I read the docs, a certain (ascending) order should not be needed.
