15 years agoI am using the ASMI block. I ported the Altera code and added a state machine to interface to my code.
So, I realized I did not have the latest user guide for the Megafunction. I downloaded that and see that Altera now lists the max clock freq for each device. For a Cyclone III it is 40Mhz. The new UG also includes an update to the READ_SOURCE table which shows a value of "11" as being the input register. That makes sense looking at the block diagram provided in the Cyclone datasheet since READ_SOURCE appears to be a mux select for the readback path. Also included is an updated table of operations which is helpful too. RTFM right? Next up is to move a new image into FLASH and hit the reconfig pin. Thanks Kevin.
