3. Software data protection
To prevent unintentional programming, this device has the software data protection (SDP) mode. The SDP
is enabled by inputting the following 3 bytes code and write data. SDP is not enabled if only the 3 bytes
code is input. To program data in the SDP enable mode, 3 bytes code must be input before write data.
