IMPORTANT: 64-megabit DataFlash.This algorithm supports 1056 bytes per Page. Please make sure the data file is in 1056 bytes per Page format.This device is set to 1056 bytes per Page by default at the factory.A seperate 1024 byte page device selection can be used for data files in 1024 bytes per Page format.***1024 and 1056 devices should not be mixed when running a job in Concurrent 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 programmed by Atmeland 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 [840000h-84003Fh]. Ifthe User Programmable Space is not blank Erase will fail on this area. The Sector ProtectionRegister can be set in Device Configure. The Security Register can be excluded from device operationsby setting Device Ranges to 0h-83FFFFh.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. ‘
