19.2.8.3 16-bit SDRAM
Figure 19-13. Hardware Configuration - 16-bit SDRAM
Software Configuration - 16-bit SDRAM
The following configuration has to be performed:
 Assign the EBI CS1 to the SDRAM controller by setting the bit EBI_CS1A in the EBI Chip Select Assignment
Register located in the bus matrix memory space.
 Initialize the SDRAM Controller depending on the SDRAM device and system bus frequency.
The Data Bus Width is to be programmed to 16 bits.
The SDRAM initialization sequence is described in Section 21.4.1 “SDR-SDRAM Initialization”.
