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...

Hello Simonhdl,

I am assuming that you have created CS8900 with its own bus in SOPC builder.

If so then connect AEN to ground and connect byteenable[1] to SBHE.

If you are using NIOS configured for 32bits then you would connect the address as follows;

Nios Address CS8900

A2 A0

A3 A1

A4 A2

Good Luck!
