Problems on connecting NIOS to CS8900

Hi, Now I'm designing a NIOS Kit with CS8900 chip. I use the CS8900 interface in the SOPC Builder directly, and I'm confuse with the byteenable[1..0] pin, 'cause there isn't any...

Thanks, but I still confuse with the Address line.

In CS8900, it use A1,A2,A3 to access the registers, so does the Nios Address line connect like this :

Nios CS8900

A2 -> A1

A3 -> A2

A4 -> A3

not the A0, A1,A2 in CS8900??

Thanks.
