Hi,

We are using the S25FL256SAGMFV001 and one of the devices FREEZE bit was set to "1" how can I set it back to "0" in the device user guide it is stated - "Once the FREEZE bit has been written to a logic 1 it can only be cleared to a logic 0 by a power-off to power-on cycle or a hardware reset" I tried to power-off-on the device but the FREEZE bit is still "1" what am I doing wrong?

Many Thanks,

HR
