This pin has multiple functions.
• For 2M byte DRAM, this is memory address bit 9 (MA9).
• For asymmetrical 512K byte DRAM, this is memory address
bit 9 (MA9).
• For symmetrical 512K byte DRAM, this pin can be used as
general purpose IO (GPIO3).
See Table 5-10: “Memory Interface Pin Mapping,” on page 32
for summary.
