"IORD_8DIRECT" reads 32 Bit ?

well after i discovered this behavioral in 2005, there were several discussion with FAE's and Altera and MySupport telling them that with this buggy feature it is nearly impossible to attach any existing profibus chip (thats an industrial network protocoll) to the tristate bridge as these devices react upon read access to some locations. some status bits a cleared and you try to dig down why as you don't understand that behavioral from software side.....

but if you and other complain about that then there might be a chance that this gets fixed but i fear this behavioral will exists for ever and ever and remain for compatibilty purposes in the future :-)

yes it is not signaltal related, i use signaltap to quick check such things without wireing some probes.
