The following configuration has to be performed:
The Data Bus Width is to be programmed to 32 bits. The data lines D[16..31] are multiplexed
with PIO lines and thus the dedicated PIOs must be programmed in peripheral mode in the PIO
controller.
The SDRAM initialization sequence is described in the “SDRAM device initialisation” 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 depending on the SDRAM device and system bus frequency.
Select Assignment Register located in the bus matrix memory space.
