of the old file will be changed to [newT] and [newID] respectively.

13.1 Introduction
Ensuring that your GLK19264-7T-1U display’s exactly what you want it to can be the difference between
a projects success and failure. This is why we incorporate features such as Data Lock into the GLK19264-
7T-1U With this new feature you now are in control over of how and when settings will be changed so there
is no need to worry about the module acting exactly like you expected it to because all the settings may be
locked and remembered for the next power up.
