This is a multi-purpose pin:
• For 2M byte DRAM, this is memory address bit 9 (MA9).
• For asymmetrical 512K byte DRAM, this is memory address bit 9
• For symmetrical 512K byte DRAM, this pin can be used as general
Note that unless configured otherwise, this pin defaults to an input and
must be driven to a valid logic level.
See “Memory Interface Pin Mapping” for summary. See Memory
Interface Timing for detailed functionality.
This is a multi-purpose pin:
• For asymmetrical 2M byte DRAM this is memory address bit 10
• For symmetrical 2M byte DRAM and all 512K byte DRAM this pin
Note that unless configured otherwise, this pin defaults to an input and
must be driven to a valid logic level.
