Hardware Configuration
In this configuration NAND Flash and DDR2-SDRAM are on the same data bus, with the same
power supply. As DDR2-SDRAM is used, NAND Flash must be 1.8V powered. So, VDDIOM and VDDNF
must be set to 1.8V.
Note: The CE signal of the NAND Flash must be connected to PIOD4
(NCS2/NANDCS) if the user's system boots out of NAND Flash.
