4.5.3 LCD RAM
LCD RAM is organisedas a LCD panel with a ma-
trix architecture. Each bit of its content is logically
mapped to a physical element of the display panel
addressed by a couple (Segment;Common). If a
bit is set, the relevant element of theLCD matrix is
turned-on. On the contrary, an element remains
turned-off as long the associated bit within the
LCD RAM is kept cleared.
After a reset, the LCD RAM is not initialised and
contain arbitrary information.
If the choosen multiplexing ratio does not use
some common plates, corresponding RAM ad-
dresses arefree for general purpose data storage.
