(display off)
Initial display line set to line 0 (L[6:0] = 0)
Initial row set to ROW 0 (C[6:0] = 0)
Full display selected (P[6:0] = mux 1 : 80 or 1 : 64)
Display is not mirrored (MX = 0 and MY = 0)
Internal oscillator is off
Power-save mode is on
No frame calibration is running.
13.3.2
E
XTENDED COMMAND SET
After reset the LCD driver has the following state:
Display settings E = 0 and DAL = 0
Icons disabled (IC = 0)
Address counter X[6:0] = 0 and Y[3:0] = 0
Temperature control mode TC2 (TC[2:0] = 010)

voltage multiplier (S[2:0] = 100)
Frame-rate frequency (FR[1:0] = 11)
After power-on, RAM data is undefined, the reset signal

All LCD outputs at V
SS
(display off)
Full display selected (P[6:0] = mux 1 : 80 or 1 : 64)
Initial display line set to line 0 (L[6:0] = 0)
Initial row set to ROW 0 (C[6:0] = 0)
Display is not mirrored (MX = 0; MY = 0)
Internal oscillator is off
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).
13.4
Power-save mode
In the power-save mode the LCD driver has the following
state:
All LCD outputs at V
SS
(display off)
Bias generator and V
LCD
generator switched off;
external V
LCD
can be disconnected
Oscillator off (external clock possible)
RAM contents not cleared; RAM data can be written
V
LCD
discharged to V
SS
in Power-down mode.
There are two ways to put the chip into power-save mode:
The display must be off (DON = 0) and all the pixels on
(DAL = 1)
The power-save mode command is activated.
13.5
Display control
The bits DON, E and DAL select the display mode;
see Table 8.
13.5.1
MX
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
MY
When MY = 1, the display is mirrored vertically.
A change of this bit has an immediate effect on the display.
