Access a 64bit component

Hi,

i've designed a 64bit component which I would like to read out from the NIOS processor. How is it possible to read this 64-bit word ? Do I need to successive 32 bit reads (IORD_32DIRECT) ? Thanks,

Christian

    I think, yes, you need to read it twice, with the proper address each time.
