Electrical and Thermal Characteristics
NOTE
Activating data pipelining (setting BRx[DR] in the memory controller)
improves the AC timing. When data pipelining is activated, sp12 can be
used for data bus setup even when ECC or PARITY are used. Also, sp33a
can be used as the AC specication for DP signals.
