OK.
So if I understand this correctly, you can (at least on some models)
write 8 bytes a time even if the prog spec specifies a 64 byte
write buffer only.

This would also mean that since the processor always write
a full 64 byte buffer, most single word/byte will be written 8
times. First 7 times with dummy ("null") data, then the 8'th
time with the correct data from the HEX file.

And also that the 64 byte programming "window" doesn't
have to be an an even 64 byte address, but can "slide"
forwards 8 bytes a time.

And, if so, the 18F8622 is very likely to be programmable
in the same way as the 18F4620. The descriptions in the
prog speces are very similar.

Interesting... :-)

Finaly, I guess one could also argue that the 8xxx class
of PICs might be slightly out of scope for the Wisp628...
