1. Ball descriptions listed in Table 3 (page 19) are listed as “x4, x8” if unique; otherwise,
2. A comma separates the configuration; a slash defines a selectable function.
x4 and x8 are the same.
Example D7 = NF, NF/TDQS#. NF applies to the x4 configuration only. NF/TDQS# applies
to the x8 configuration only—selectable between NF or TDQS# via MRS (symbols are de-
fined in Table 3).
