Connecting SDRAM/FCRAM to Many Areas

This section shows the connecting SDRAM/FCRAM to many areas.
■ Connecting SDRAM/FCRAM to Many Areas
SDRAM/FCRAM can be set for CS6 and CS7 areas. When connecting SDRAM/FCRAM to 2
areas, connect the same type of modules.
More precisely, connect the modules common in the following register settings.
• Area configuration register (ACR): Set all of the DBW1 to DBW0, BST1 to BST0, and TYP3
• Area wait register (AWR):
• Memory setting register (MCR):
• Refresh control register (RCR):
To enable the two areas at a time, execute the power-on sequence, auto-refresh, and self-
refresh at the same time.
