1. Ball descriptions listed in Table 4 (page 21) are listed as “x4, x8” if unique; otherwise,
x4 and x8 are the same.
Notes:
2. A comma separates the configuration; a slash defines a selectable function.
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 4).
