Comment

Set the lower nibble of the colume address register using

X3X2X1X0 as data bits. The initial display line register is reset to

0000b during POR.

Set the higher nibble of the colume address register using

X3X2X1X0 as data bits. The initial display line register is reset to

0000b during POR.

Internal regulator gain increases as X2X1X0 increased from 000b

to 111b. At 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

Set display RAM display start line register from 0-63 using

X5X4X3X2X1X0.

Display start line register is reset to 000000 during POR.

Set Contrast level from 64 contrast steps. Contrast increases (VL6

decreases) as X5X4X3X2X1X0 is increased.

X5X4X3X2X1X0 = 100000b (POR)

X0=0: column address 00h is mapped to SEG0 (POR)

X0=1: column address 83h is mapped to SEG0

Refer to Figure 5 for example.

X0=0: 1/9 bias (POR)

X0=1: 1/7 bias

For setting bias ratio to 1/4, 1/5, 1/6 or 1/8, see Extended Com-

mand Table.

X0=0: normal display (POR)

X0=1: entire display on

X0=0: normal display (POR)

X0=1: reverse display

X0=0: turns off LCD panel (POR)

X0=1: turns on LCD panel

Set GDDRAM Page Address (0-8) using X3X2X1X0

X3=0: normal mode (POR)

X3=1: remapped mode, COM0 to COM[N-1] becomes COM[N-1]

to COM0 when Multiplex ratio is equal to N. See Figure 5

as an example for N equal to 64.

Read-modify-write mode will be entered in which the column

address will not be incremented during display data read. At POR,

Read-modify-write mode is turned OFF.

Initialize the internal status register.

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

mode will be restored. At POR, Read-modify-write mode is OFF.

X0 = 0: indicator off (POR, no need of second command byte)

X0 = 1: indicator on (second command byte required)

Indicator Display Mode,

X1X0 = 00: indicator off

This second byte command is required X1X0 = 01: indicator on and blinking at ~1 second interval

ONLY when “Set Indicator On” com- X1X0 = 10: indicator on and blinking at ~1/2 second interval

mand is sent.

X1X0 = 11: indicator on constantly
