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.
