External RAM access via 16-bit multiplexed bus

Hello! I have problem with external memory access on XC167CI. The external RAM is organized on PLD. Need about 1 KB (64 kb non segment memory). I use 2-byte variables (unsigned int) to store on external RAM and 16-bit multiplexed bus. The address of one variable is 0x0400 - this is 16-bit address. In start_v2.a66 i check CS1 for start address is 0x000000. I use unsigned int near pointers. What settings i must do in CS1? And what types of variables and pointers to use for it?
