2x8-bit DDR2 on EBI
The DDR2 initialization sequence is described in the sub-section “DDR2 Device Initialization” of
the DDRSDRC section.
In this case VDDNF can be different from VDDIOM. NAND Flash device can be 3.3V or 1.8V
and wired on D16-D31 data bus. NFD0_ON_D16 is to be set to 1.
• Assign EBI_CS1 to the DDR2 controller by setting the EBI_CS1A bit in the EBI Chip Select
• Initialize the DDR2 Controller depending on the DDR2 device and system bus frequency.
Register located in the bus matrix memory space.
