3.10.4 Save
Figure 22. Save Function
The Save feature gives the user the ability to save the Serial EEPROM memory array. The memory array can be
saved as either a HEX (.hex) file or TEXT (.txt) file based on the user preference. Once a file type is selected, a file
explorer will pop up and save the file.
3.10.5 Program
Figure 23. Program Function
The Program function can be used to write to the Serial EEPROM memory, the Security Register, Lock Zone 0 to
Zone 3, and even lock the User Space of the Security Register.
When the Program button is pressed, the Graphical UI buffer is written to the Serial EEPROM memory. The Program
button must be pressed when a cell is updated, or when a file (.hex or .txt) is loaded. If the program button is not
pressed, and the Graphical UI is stopped, the data in the buffer will not be written to the Serial EEPROM memory.
The Program button can also be used to lock the four memory zones and the Security Register. Please refer to
