20.3.8.2 16-bit LPDDR on EBI
Hardware Configuration
Software Configuration
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
Register located in the bus matrix memory space.
• Initialize the DDR2 Controller depending on the LP-DDR device and system bus frequency.
The LP-DDR initialization sequence is described in the section “Low-power DDR1-SDRAM Ini-
tialization” in “DDR/SDR SDRAM Controller (DDRSDRC)”.
