No connect: These balls should be left unconnected.
No function: x8: these balls are used as DQ4–DQ7; x4: they are
no function.
Not used: If EMR(E10) = 0: x16, A8 = UDQS# and E8 = LDQS#;
x8, A2 = RDQS# and A8 = DQS#; x4, A2 = NU and A8 = NU. If
EMR(E10) = 1: x16, A8 = NU and E8 = NU; x8, A2 = NU and
A8 = NU; x4, A2 = NU and A8 = NU.
