Comment

X0=0: turns off LCD panel (POR)

X0=1: turns on LCD panel

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

X5X4X3X2X1X0.

Display start line register is reset to 000000 during POR.

Set GDDRAM Page Address (0-8) using X3X2X1X0

Set the higher nibble of the colume address register using

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

0000 during POR.

Set the lower nibble of the colume address register using

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

0000 during POR.

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

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

Refer to Fig. 5 for details.

X0=0: normal display (POR)

X0=1: reverse display

X0=0: normal display (POR)

X0=1: entire display on

X0=0: 1/8 bias (POR)

X0=1: 1/6 bias

For setting bias ratio to 1/4, 1/5, 1/7 or 1/9, see Extended Com-

mand Table.

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

address will not be incremented during display data read

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

the mode will be restored

Initialize the internal status

X3=0: normal mode (POR)

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

to COM0 in Multiplex ratio is equal to N. See Fig.5 as an

example for N equal to 56.

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

Internal regulator gain increases as X2X1X0 increased from 000b

to 111b. X2X1X0 = 100b (POR)

Set Contrast level from 64 contrast steps. Contrast increases as

X5X4X3X2X1X0 is increased.

X5X4X3X2X1X0 = 100000b (POR)

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

X1X0 = 01: indicator on and blinking at ~1 second interval

This second byte command is required X1X0 = 10: indicator on and blinking at ~1/2 second interval

ONLY when “Set Indicator On” com- X1X0 = 11: indicator on constantly

mand is sent.

Set Power Save Mode

Standby or sleep mode will be entered with compound commands

NOP

Command for No Operation

Set Test Mode

Reserved for IC testing. Do NOT use.

Test Mode Reset

Reserved for IC testing. Do NOT use.
