Description
0000X3X2X1X0
Set Lower Column Address
Set the lower nibble of the column address register
using X3X2X1X0 as data bits. The lower nibble of
column address is reset to 0000b after POR
0001X3X2X1X0
Set Higher Column Address
Set the higher nibble of the column address register
using X3X2X1X0 as data bits. The higher nibble of
column address is reset to 0000b after POR.
00100X2X1X0
Set Internal Regulator Resistor Ratio
Feedback gain of the internal regulator generating
VL6 increases as X2X1X0 increased from 000b to
111b. After POR, X2X1X0 = 100b
00101X2X1X0
Set Power Control Register
X0=0: turns off the output op-amp buffer (POR)
X0=1: turns on the output op-amp buffer
X1=0: turns off the internal regulator (POR)
X1=1: turns on the internal regulator
X2=0: turns off the internal voltage booster (POR)
X2=1: turns on the internal voltage booster
01X5X4X3X2X1X0
Set Display Start Line
Set GDDRAM display start line register from 0-63
using X5X4X3X2X1X0.
Display start line register is reset to 000000 after
POR.

Set Contrast Control Register
Select contrast level from 64 contrast steps.
Contrast
increases
(VL6
decreases)
as
X5X4X3X2X1X0 is increased from 000000b to
111111b.
X5X4X3X2X1X0 = 100000b after POR
1010000X0
Set Segment Re-map
X0=0: column address 00h is mapped to SEG0
(POR)
X0=1: column address 67h is mapped to SEG0
Refer to Table 4 on page 12 for example.

For other bias ratio settings, see “Set 1/4 Bias Ratio”
and “Set Bias Ratio” in Extended Command Set.

Set Entire Display On/Off
X0=0: normal display (POR)
X0=1: entire display on
1010011X0
Set Normal/Inverse Display

X3=0: normal mode (POR)
X3=1: remapped mode,
COM 0 to COM [N-1] becomes COM [N-1] to COM 0
when Multiplex ratio is equal to N.
See Figure 5 on page 17 for detail mapping.
