2. 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. IssuingtheAllSPBErasecommandwilleraseallSPBinthesametime.DuringSPBprogrammingperiod,the readandwriteoperationsaredisabledfornormalsectoruntilthismodeexits. If one of the protected sector need to be unprotected (corresponding SPB set to "1"), a few more steps are required.First,theSPBLockBitmustbeclearedbyeitherputtingthedevicethroughapower-cycle,orhardware reset.TheSPBscanthenbechangedtoreflectthedesiredsettings.SettingtheSPBLockBitonceagainlocks theSPBs,andthedeviceoperatesnormallyagain. To verify the programming state of the SPB for a given sector, issuing a SPB Status Read Command to the deviceisrequired.RefertotheflowchartbelowfordetailsofSPBProgramAlgorithm. Notes 1.TheReadactionswithinthatsectorwillbringtheSPBstatusbackforthatsector.AllReadactionsmustbe executedbyreadmode.Thespecificsectoraddressiswrittenastheprogramcommandatthesametime. 2.Once SPB Lock Bit is set, its Program or erase command will not be executed and times-out without programmingorerasingtheSPB. 3.Alwaysissueexitcommandaftertheexecutionofresettingthedevicetoreadmodeandre-enablesreadand writeactionsfornormalarray. 4.Toachievethebesteffectofprotection,itisrecommendedtoexecutetheSPBLockBitSetcommandearly inthebootcodeandprotectthebootcodebyholdingWP#/ACC=VIL.NotethattheSPBandDPBbitshave thesamefunctionwhenWP#/ACC=VHH,anditissamewhenACC=VIH.
2.2 Dynamic Protection Bits (DPBS) The Dynamic Protection allows the software application to easily protect sectors against inadvertent change. 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.

2.3 Temporary Un-protect Solid write protect bit (USPB) Temporary Un-protect Solid write Protect Bits are volatile and unique for each sector and can be individually modified.

3. Solid Protection Bit Lock Bit The Solid Protection Bit Lock Bit (SPB) is assign to control all SPB status. 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. There is no software command sequence requested to unlocks this bit, unless the device is in the password protectionmode.TocleartheSPBlockbit,justtakethedevicethroughahardwareresetorapower-upcycle.In ordertopreventmoified,theSPBLockBitmustbeset(SPB=0)afterallSPBsaresettingthedesiredstatus.

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.

Thepasswordisall"1"swhenshippedfromthefactory,itisonlycapabletoprogramming"0"sunderpassword program command.All 64-bit password combinations are valid as a password. 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.
