Description 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 After deleting the ﬁle system it is important to cycle power to your display to

ensure the removal process is completed.
