16-bit SDRAM
Hardware Configuration
Software Configuration
The following configuration has to be performed:
The Data Bus Width is to be programmed to 16 bits.
The SDRAM initialization sequence is described in the “SDRAM Device Initialization” part of the
SDRAM controller.
• Assign the EBI CS1 to the SDRAM controller by setting the bit EBI_CS1A in the EBI Chip
• Initialize the SDRAM Controller accordingly to SDRAM device and system bus frequency.
