SDRAM Controller
Table 9-2
9.3
The following tables describes possible memory configurations using most common SDRAM devices for
16- and 32-bit wide data buses.
A device’s data bus width affects its connection to SDRAM address pins. A device can be configured for
external data bus width of 16 or 32 bits by appropriate configuration of the WSEL signal during reset. See
Section 19.18, “Operating Mode Configuration
connections and internal address multiplexing.
