IMPORTANT: Microcontroller with EPROM.Default buffer value must be set to 255(FFh). The EncryptBuf is used on read back. If the Encryption arrayhas been programmed EncryptBuf must contain the correct encryption key to read the device properly. If encryptionis not being used on this device all 64 bytes in the EncryptBuf should be set to 255(FFh).You must select the appropriate security mode under DEVICE/OPTIONS to operate the secure command.Three lock bits are available in this chip: LB1 LB2 and LB3. Mode1′ programs LB1 ‘Mode2’ programs LB1 and LB2 and ‘Mode3’ programs all lock bits.These lock bits are not erasable.!!!Note: If both Encryption and Secure functions are required they must both be enabled.GANG Serialization Not Currently Supported.To Read Decrypted Data you must perform the following tasks:1) Clear the buffer.2) Enter the encryption password.3) Deselect the Clear Buffer First option. ‘
