SDRAM Controller and NOP/DESLECT Commands

I have a MCF5329 processor and an ISSI IS43R1632D SDRAM. I am having problems initializing the SDRAM. The procedure from ISSI mentions issuing NOP or DEESLECT commands. How do I do this using the SDRAMC? Is it a matter of writing to the SDMR without setting the CMD bit?
