No, it is not a typo.  Why do you think it is typo?


Page 91. M7261. E102 / A04A2.

When comparing my chip, which I removed and dumped, it is very different
from the listing. Maybe half the chip differs. The problems in the
microcode flow definetely matches the contents of the dump.
I am getting a little worried that there are different versions of the
microcode. Anyone knows of different versions?
