Comment

Set GDDRAM Page Address using X 3X2X1X0 as address bits.

X3X2X1X0=0000 : page 1 (POR)

X3X2X1X0=0001 : page 2

X3X2X1X0=0010 : page 3

X3X2X1X0=0011 : page 4

X3X2X1X0=0100 : page 5

X3X2X1X0=0101 : page 6

X3X2X1X0=0110 : page 7

X3X2X1X0=0111 : page 8

X3X2X1X0=1000 : page 9

Next Command (byte) on D5 ~ D0 defines the display rows loca-

tion.

Starts at Row0 - COM0 (POR)

X0=0 : Enable 2X Converter

X0=1 : Enable 3X Converter

Remark: This command overrides “Set 4X/5X DC-DC Converter”.

Set one of the 16 contrast level values using X3X2X1X0 as data

bits. Reset to 0000 during POR.

X0=0: Enable 4X Converter (POR)

X0=1: Enable 5X Converter

Remark: This command overrides “Set 2X/3X DC-DC Converter”.

X0=0 : Column 0 to SEG0 (POR)

X0=1 : Column 0 to SEG159

X0=0 : Row 0 to Display Row location (POR)

X0=1: Flip the Row-COM mapping.

X0=0: MSB = 0 (POR)

X0=1: MSB = 1

X0=0: Display off (POR)

X0=1: Display on

X0=0: Disable Voltage Generator (POR)

X0=1: Enable Voltage Generator

X0=0: Disable Regulator (POR)

X0=1: Enable Regulator

When application uses a supply with built-in temperature compen-

sation, the regulator should be disabled.

X0=0: Disable Voltage Divider (POR)

X0=1: Enable Voltage Divider

When an external bias network is preferred, the voltage divider

should be disabled.

X0=0: Disable Internal Contrast Control(POR)

X0=1: Enable Internal Contrast Control

Internal contrast circuits can be disabled if external contrast cir-

cuits is preferred.

X0=0 : Normal display frequency (POR)

X0=1 : Half display frequency

X0=0 : Restore address

X0=1 : Save address
