[wapayk]

Hi all,

I am trying to read JEDEC fuse map from ispLSI 1032E but i get JEDEC file with all fuses set as 0.
Chip ID is correct.

Has anybody had this kind of problem.
I am using LPT download cable

ispLSI1032 supports design security. If the security fuse is set, the device can't be copied. I don't know however, if the fuse array is displayed as all 00 or FF in this case.

Thank you very much for quick ansfer, it seams that chip is protected.
Is there some information in jdec file I downloaded if this protection fuse is set or not. Where while I look. I am using ispVM to program and read lattice chips.
