LCD row/column driver for dot matrix graphic displays
The display status (all dots on or off and normal or inverse video) is set by the bits E[1:0]
of the set-mode command. For bank switching, the RAM bank corresponding to the top of
the display is set by the bits B[1:0] of the set-start-bank command. This is shown in
Figure 20. This feature is useful when scrolling in alphanumeric applications.
