Install DIMM Module
A 256-Mbyte DIMM is shipped with the platform. Install this memory module (when the platform is
powered down) onto the DIMM connector U1 as shown in Figure 30 . This DIMM connector can
accommodate 64-MByte to 1-GByte modules. The MPC8349E reads the DDR serial presence detect
(SPD) data from the EEPROM on the DIMM module to identify the module type and various SDRAM
configurations and timing parameters.
