Product data sheet
12.5.1 Bit MX
12.4 Power-save mode
12.5 Display control
In the Power-save mode the LCD driver has the following state:
There are two ways to put the chip into Power-save mode:
The bits DON, E and DAL select the display mode; see
When MX = 0 the display RAM is written from left to right (X = 0 is on the left side and
