Interface to SDRAM Devices
Table 9-2 shows how BS[3:0] should be connected to DQMx for 16- and 32-bit SDRAM
configurations.
9.3 Interface to SDRAM Devices
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 Pins.” The
following tables describe address pin connections and internal address multiplexing.
