Solid write (non-volatile) protection Mode 2.1 Solid write Protection Bits (SPB) The Solid write Protection bit (SPB) is a nonvolatile bit with the same endurances as the Flash memory. It is assigned to each sector individually. The SPB is Preprogramming, and its verification prior to erasure are managedbythedevice,sosystemmonitoringisnotnecessary. WhenaSPBissetto"0",theassociatedsectorisprotected,preventinganyprogramoreraseoperationonthis sector.TheSPBbitsaresetindividuallybySPBprogramcommand.However,itcannotbeclearedindividually.

However,theprotectioncanbeeasilydisabledwhenchangesarenecessary. All Dynamic Protection bit (DPB) are volatile and assigned to each sector. It can be modify individual. DPBs provide the protection scheme only for unprotected sectors that have their SPBs cleared (erase can be individually modified d to "1").To modify the DPB status by issuing the DPB Set (programmed to "0") or DPB Clear(erasedto"1")commands,thenplacingeachsectorintheprotectedorunprotectedstateseperately.After theDPBClearcommandisissued(erasedto"1"),thesectormaybemodifieddependingontheSPBstateofthat sector Whenthepartsarefirstshipped,theSPBsarecleared(erasedto"1")anduponpoweruporreset,theDPBscan besetorcleareddependingupontheorderingoptionchosen.

It is a unique and volatile. When SPB=0 (set), all SPBs are locked and can not be changed. When SPB=1 (cleared), all SPBs are unlock and allowstobechanged.

The PasswordUnlockcommandareissuedslowerthen2severytime,.topreventhackerfromtryingallthe64-bit passwordcombinations. To place the device in password protection mode, a few more steps are required. First, prior to entering the password protection mode, it is necessary to set a 64-bit password to verify it. Password verification is only allowedduringthepasswordprogrammingoperation.Second,thepasswordprotectionmodeisthenactivated by programming the password the Password Protection Mode Lock Bit to"0". This operation is not reversible. Oncethebitisprogrammed,itcannotbeerased,andthedeviceremainspermanentlyinpasswordprotection mode, and the 64-bit password can neither be retrieved nor reprogrammed.

No special address is required for programming the password. In order to prevent access, the Password Mode Locking Bit must be set after the Password is programmed and verified.
