Hi,

the parallel interface is explained in the document "Altera User Flash Memory (ALTUFM) IP Core User Guide", you can get it from here: https://www.altera.com/en_us/pdfs/literature/ug/ug_alt_ufm.pdf (https://www.altera.com/en_us/pdfs/literature/ug/ug_alt_ufm.pdf). Unfortunately there are no waveform examples for the parallel interface, but it seems to be pretty straightforward - wait until "busy" is 0, then apply "addr" and strobe "nread", wait until "data_valid" is 1, then get your data from "do". If in doubt you can also write a small testbench and simulate it in ModelSim.

Best regards,
