IMPORTANT: This algorithm only supports standard devices. 256Mbit (16M x 16) Intel StrataFlash(R) Memory.This device contains 17 128-bit Protection Registers PR0 through PR16 located at address range[2000000h-200010Fh] in the buffer. Example: PR0[0x81-0x88] is located at [2000000h-200000Fh]PR1[0x8A-0x91] at [2000010h-200001Fh] and so on.PR0[63:0] are permanently programmed by Intel with a unique number for each flash device.PR0[127:64] and PR1 through PR16 are one-time programmable (OTP) and available for the user to program.If one or more OTP registers are programmed the range must be set to exclude the registers orErase/Program will fail.Once programmed the user-programmable register can be locked to prevent further programming usingDevice Configure menu. Once the protection register is locked the entire user segment is lockedand no more user bits may be programmed.The default Device Range is set to [000000h-FFFFFFh]. Please select Entire File’ under Device Range if Protection Registers need to be included.’Verify after programming’ operation is redundant per Intel and can be set to ‘NONE’ under Device Optionsfor faster programming time. ‘
