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 section “SDRAM Device Initialization” in
“SDRAM Controller (SDRAMC)”.
In this case VDDNF must to be equal to VDDIOM. The NAND Flash device must be 3.3V and
wired on D0-D15 data bus. NFD0_ON_D16 is to be set to 0.
• 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.
