IMPORTANT: This algorithm supports 256-byte per Page.264-byte configured devices are converted to 256-byte mode before any operations are executed. This conversionis permanent. Once a device is converted to 256-byte mode it can not be changed back to 264-byte mode.Erase before programming must be enabled if the state of the deviceis uncertain. The device has a 128-byte Security Register. The first 64 bytes arethe one-time user programmable space and the remaining 64 bytes are factory programmedand will contain a unique number for each device. The factory programmed data is fixed and cannotbe changed. The User Programmable Space is located in Buffer addresses [80000h-8003Fh]. Ifthe User Programmable Space is not blank Erase will fail on this area. The Sector ProtectionRegister can be set in Device Configure.The default Device Range is set to [00000h-7FFFFh].Please select Entire File’ under Device Range if Security Register needs to be included.Sector LockDown can be set in Device Configure. Once a sector is locked down Erase and Program will fail.The sector then cannot be unlocked.The ‘ Power of 2’ binary page size Configure Register can be set using Secure. The ‘ Power of 2’page size is a One-time Programmable(OTP)register and once the device is configured for page size it can notbe reconfigured again. ‘
