Figure 19-12. Hardware Configuration - 16-bit LPDDR on EBI
Software Configuration - 16-bit LPDDR on EBI
The following configuration has to be performed:
 Assign EBI_CS1 to the DDR2 controller by setting the bit EBI_CS1A in the EBI Chip Select Assignment
Register located in the bus matrix memory space.
 Initialize the DDR2 Controller depending on the LPDDR device and system bus frequency.
The LPDDR initialization sequence is described in Section 21.4.2 “Low-power DDR1-SDRAM Initialization”.
