Hi again Finn.
I=E2=80=99m really rusty as far as my embedded system knowledge, but we =
may find the chips config data at the end of the List file.
Look  at the end of the ec3cl8.lst file. We ay be able to find the chips =
config data from the SYMBOL TABLE LABEL and its associated VALUE.
Can MPLABS read the last file? As I said, I=E2=80=99m very rusty.
Steve
