Figure 2–7. Memory Interface

Figure 2–8. Datapath Interface

Figure 2–8 shows that any read data captured on the rising edge of the

delayed rldramii_qk[] signal is located in the lower half-bit locations

of control_rdata[]. Any read data captured on the falling edge of the

delayed rldramii_qk[] signal is located in the upper half-bit locations
