Failure of modification to altera example an494 with register adddress.

I use the an494 design example to GPIO Pin Expansion Using I2C Bus Interface in Altera MAX V and the connection works well between the slave MAX V and my master device, but it only have function with slave address and byte data, don't have register address matching logic. So I modify the logic by adding register address logic, but it doesn't work.

Hi,

In this app note there only one slave contains only 7'h0 , so no register address is required.

I want to know why my verilog file failed with adding register address.
