No data being sent if WRITE_FIFO = 0

[lranders]

There seems to be an issue that only shows itself if the write-through fifo for data is disabled.

The data_in_valid_int net seems to be dangling w/o a driver and thus gets assigned to GND.

Would it be correct to assume you're missing an _int at the left hand side end of the assignment?

I am thinking this issue is similar to #1, fixed in 2017. I hope you're still around and well Alex...
