Note:
Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal. Timings are
measured at the pin.

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 specification for DP signals.
Note: There are four possible TDM timing conditions:
1. Input sampled on the rising edge and output driven on the rising edge (shown).
2. Input sampled on the rising edge and output driven on the falling edge.
3. Input sampled on the falling edge and output driven on the falling edge.
4. Input sampled on the falling edge and output driven on the rising edge.
