SiLabs F340 EMIF for External Device Access

I am using the uVision 3 (ver. 3.72) tool and working with a Silicon Labs 8051F340 MCU. I need to map a device (an FPGA with registers) into external memory and access it with the MCU. There are not very many FPGA registers to access.

I am trying to use Split Mode without Bank Select and a multiplexed address/data bus. I'm looking for some guidance in setting up the target options, startup assembly code, and anything else that's necessary.

I have code compiling which is basically:

volatile uint8_t xdata *fpga_reg = (volatile uint8_t xdata *)0x1000;

...

*fpga_reg = 0x12;

Thanks in advance for any help.
