NF
No Function: These pins are used as DQ4–DQ7 on the 64 Meg x 8,
but are NF (No Function) on the 128 Meg x 4 configuration.
D8, H8
NU
Not Used: Not used only on x16. If EMR[E10] = 0, D8 and H8 are
UDQS# and LDQS#.
If EMR[E10] = 1, then D8 and H8 are not used.
H2, H8
NU
Not Used: Not used only on x8. If EMR[E10] = 0, H2 and H8 are
RDQS# and DQS#.
If EMR[E10] = 1, then H2 and H8 are not used.
