Thanks!
that it will...
Without fully understanding things, I'm guessing so too, especially if my suspicion that the Spartan-3 is related to the Virtex-II in some important way; that sounds familiar now. Suppose I could look it up, but I'm too busy now making up for lost time!
Anyway, I was going to say I don't have time to try, but since you've been so good to me, I figure I could return the favor. Yes, the second method does indeed work! Seems to suggest there are two separate uses of this function, one which the FPGA requires pulses for whatever reason, and the other just time (erasing flash?)...
Take care, Bob
