What To Do With Unused Pins ADSP-21489

Hi, I am working on a custom board for the ADSP-21489 and am wondering what I should do with the pins I am not using. Mainly I am wondering about the external SDRAM interface, since I am not using that at all. I am also wondering about the IRQ pins and the WDT pis. Should these pins be tied low, tied high or left unconnected? 


I have consulted the hardware reference manual and the datasheet for the ADSP-21489, but neither have a clear answer for what to do with pins when they are unused. 


Please let me know where I can find this information.
