3.4.9 DDR2 memory controllers, DMC-400

The DMC-400 AXI interface runs asynchronously to the internal NIC-301 AXI interconnect,

by default, at the frequency that the daughterboard oscillator, OSCLK 8, defines. See:

• Top-level view of the Cortex-A15_A7 MPCore test chip components on page 2-4

• Figure 2-10 on page 2-26.
