In the power-save mode the LCD driver has the following
state:
There are two ways to put the chip into power-save mode:
13.5
The bits DON, E and DAL select the display mode;
see Table 8.
13.5.1
When MX = 0 the display RAM is written from left to right
(X = 0 is on the left side and X = X max is on the right side
of the display).
When MX = 1 the display RAM is written from right to left
(X = 0 is on the right side and X = X max is on the left side
of the display).
The MX bit has an impact on the way the RAM is written
to. So if a horizontal mirroring of the display is desired, the
RAM must first be rewritten, after changing the MX bit.
13.5.2
When MY = 1, the display is mirrored vertically.
A change of this bit has an immediate effect on the display.
Power-save mode is on
Horizontal addressing enabled (V = 0)
No data order swap (DOR = 0)
No bottom row swap (BRS = 0)
Internal oscillator enabled (EC = 0)
No frame calibration running (OC = 0).
