EPCQL512 Status Register Bits 7 is on. What is bit 7 and how to turn it off ?

Can't make change to the protect bits 2-6 (BP0, BP1, BP2, BP3 and TB) anymore. There is no information on the Status Register Bits 7 in "EPCQ-L Serial Configuration Devices Datasheet"

Hi MShafiq, I tried to erase with a JIC file which include both the “Used Bitstream’ and “Non-Used Bitstream”, but it failed due to protected sectors. [cid:image006.png@01D5179C.DF734C30] [cid:image001.png@01D5179B.6D329960] Status Register bit 7 got stucked and I can’t change it protect bit anymore. Thanks, Steven
