XA-H4 Setup for 16Mb DRAM

Question:
The standard 4Mx16 DRAMs available today come in two different types: those with 12 rows and 10 columns and those with 13 rows and 9 columns. Which part does the XA-H4 support and what setup values are needed?

Answer:
For the XA-H4, use the 12 row by 10 column parts. The bank setup values are:
BxCFG = 0xff, Code/Data/16bit/DRAM with 8M depth
BxAM = 0x02, Based at 0x00000, mux setup for 8M depth
BxTMG = 0xde

Below is an example of the address and data bus connections to a typical DRAM.
