AMENDMENT
SUMMARY
This amendment adds information to the Final Data
Sheet on the Commercial and Industrial 20 MHz speed
grades. This latest offering complements the 8, 10, and
16 MHz speed grades currently offered by AMD.
A few minor inaccuracies are also corrected and a clari-
fication section on Hardware Reset in Software that had
been previously available as a separate page is now re-
printed here for ease of reference.
