Hi, I am having a problem with a design. When DONE cycle is set to 5 or 6 DONE pin never goes high. I have confirmed that the part is configuring by scoping the output from the DCM. The part is a 2S300E.
When I scope out the INIT line I find that after 280mS the INIT line returns to a High-Z state - I believe that this is interupting the state machine so causing the DONE pin not to go high.
If I set the DONE cycle to 1, 2, 3 or 4 - DONE goes high and INIT stays high.
Any help would be appreciated
Dave
