Hardware Configuration
Software Configuration
16-bit SDRAM
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 section “SDRAM Device Initialization” in
“SDRAM Controller (SDRAMC)”.
• Assign the EBI CS1 to the SDRAM controller by setting the bit EBI_CS1A in the EBI Chip
• Initialize the SDRAM Controller depending on the SDRAM device and system bus frequency.
Select Assignment Register located in the bus matrix memory space.
