This command completely erases the display’s non-volatile memory. It
removes all fonts, font metrics, bitmaps, and settings (current font,
cursor position, communication speed, etc.). It is an “odd” command in
that it is three bytes in length in order to prevent accidental execution.
NOTE
ensure the removal process is completed.
Yes
This command erases a single file at a time within the
GLK19264-7T-1U memory when given two parameters: [type] and

saved to the GLK19264-7T-1U.
NOTE After deleting a file it is important to cycle power to your display to ensure file
system integrity.
