SDRAM Memory Controller (SDRAM)
The SDRAM controller must be configured properly in the MPC5200 system to enable RAM operation, which is crucial for vast
majority of applications. As it is not always easy to determine the proper SDRAM controller settings for a given memory device,
the GCT contains a database of valid settings for the most commonly used SDRAM and DDRAM devices.
The central portion of the SDRAM GCT page displays the SDRAM settings for the selected memory device and a clock speed
as retrieved from the database. The user is not allowed to modify the settings unless he knowingly enables it using the check-
box at the bottom side of the page. When modified, the database can be updated with a new values. A database is saved as a
standard “INI” file named “sdram.ini” located in the “sdram” sub-directory of the GCT application folder. An advanced user can
use a text editor to modify or to add new entries to the database.
