Data Masks 8:0
The data write masks, associated with one data byte. In Write mode,
DM operates as a byte mask by allowing input data to be written if it is
LOW but blocks the write operation if it is HIGH. In Read mode, DM
lines have no effect.

Serial Bus Clock
This signal is used to clock data into and out of the SPD EEPROM.
Serial Bus Data
This is a bidirectional pin used to transfer data into or out of the SPD
EEPROM. A resistor must be connected from SDA to
V
DDSPD
on the
motherboard to act as a pull-up.
Serial Address Select Bus 2:0
These signals are tied at the system planar to either
V
SS
or
