The DDR controller and DDR PHY are connected via DDR PHY Interface (DFI) which is used for transferring control information and data between the PHY and the controller. There are DFI programmable parameters which software can interact with through some of the DDR controller (see DDR Controller Registers), PI (see PI Registers) and DDR PHY (see DDR PHY Registers) registers. For more information about DFI, see http://www.ddr-phy.org/.
