Notes:

1. Ball descriptions listed in Table 3 (page 18) are listed as “x4, x8” if unique; otherwise,

x4 and x8 are the same.

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 3).
