Implementation Examples
2x8-bit DDR2 on EBI
The following hardware configurations are given for illustration only. The user should refer to the
memory manufacturer web site to check current device availability.
The DDR2 initialization sequence is described in the sub-section “DDR2 Device Initialization” of
the DDRSDRC section.
• 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.
