0000X3X2X1X0

Set Lower Column Address

Set the lower nibble of the column address register using X3X2X1X0 as data

bits. The initial display line register is reset to 0000b after POR.

0001X3X2X1X0

Set Higher Column Address

Set the higher nibble of the colume address register using X3X2X1X0 as data

bits. The initial display line register is reset to 0000b after POR.

00100X2X1X0

00101X2X1X0

100X4X3X2X1X0

Set Internal Regulator Resistor Ratio

Set Power Control Register

Set Contrast Control Register

Feedback gain of the internal regulator generating VL6 increases as X2X1X0

increased from 000b to 111b.

After POR, X2X1X0 = 100b.

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

Sets one of 32 available values to the internal contrast control register using

X4X3X2X1X0. Maximum ± 4% VL6 output variation among the 32 levels should

be considered.

Recommend to use level 10010000b [90] as the center contrast control for

smaller output variance. The contrast control register is reset to 10000000b

after POR.

1010000X0

Set Segment Re-map

When Mode = 1: (34 mux)

X0=0: column address 12H is mapped to SEG2 (POR)

X0=1: column address 71H is mapped to SEG2

When Mode = 0 or NC (32 mux)

X0=0: column address 10H is mapped to SEG0 (POR)

X0=1: column address 73H is mapped to SEG0

Set Display On/Off

X0=0: 1/6 bias (POR)

X0=1: 1/5 bias

X0=0: normal display (POR)

X0=1: entire display on

X0=0: normal display (POR)

X0=1: inverse display

X0=0: turns off LCD panel (POR)

X0=1: turns on LCD panel

Set Page Address

Set COM Output Scan Direction

Set GDDRAM Page Address (0~8) for read/write using X3X2X1X0

X3=0: normal mode (POR)

X3=1: remapped mode. COM0-33 become COM33-0.

See Figure 8 on page 16 for detail mapping

11100000

Set Read-Modify-Write Mode

Read-modify-write mode will be entered in which the column address will not be

increased during display data read. After POR, Read-modify-write mode is

turned OFF.

11100010

Software Reset

Initialize the internal status

11101110

Set End of Read-Modify-Write Mode

Exit Read-modify-write mode. Column address before entering the mode will be

restored.After POR, Read-modify-write mode is turned OFF.

Set Indicator On/Off

Set Test Mode

X0=0: indicator off (POR)

X0=1: indicator on

********

Set Power Save Mode

(Standby or Sleep)

Standby or sleep mode will be entered using compound commands.

Issue compound commands “Set Display Off” followed by “Set Entire display

On”.

01X5X4X3X2X1X0

Set Vertical Scroll Register

Set the vertical scroll value from 0-63 using 01X5X4X3X2X1X0 when Vertical

Scroll Value Range Register is set to 0.

The Vertical Scroll Register is reset to 01000000 after POR.
