The product embeds two DDRSDR controllers: DDRSDRC0 and DDRSDRC1.
Figure 19-1. DDRSDR Controllers
 DDRSDRC0 is a multi-port DDRSDR controller, standalone. It supports only DDR2 and LPDDR devices. Its
user interface is located at 0xFFFFE600.
 DDRSDRC1 is a single-port DDRSDR controller, embedded in EBI. It supports DDR2, LPDDR, SDR and
LPSDR devices. Its user interface is located at 0xFFFFE400.
Both are described in Section 21. “DDR SDR SDRAM Controller (DDRSDRC)”.
All references to SDR and LPSDR must be ignored for DDRSDRC0, multi-port DDRSDR controller.
All references to multi-port must be ignored for DDRSDRC1, DDRSDR controller embedded in EBI.
