Comment

X0=0 : normal display mode (POR)

X0=1 : icon display mode

X0=0 : restore address

X0=1 : save address

Master clear page 1 and 2 of GDDRAM, dummy write is required

after this command.

Master Clear of GDDRAM page 3.

GDDRAM page 3 should be selected and dummy write is required

X0=0: normal display frequency

X0=1: slow display mode

X0=0: normal operation (POR)

X0=1: test mode

(Note: Make sure to set X0=0 during application)

Use X3X2X1X0 as number of lines to scroll.

Scroll value = 0 upon POR

A1A0=00: select annunciator 1 (POR)

A1A0=01: select annunciator 2

A1A0=10: select annunciator 3

A1A0=11: select annunciator 4

X0=0: turn selected annunciator off (POR)

X0=1: turn selected annunciator on

Set horizontal scrolling mode. The next input from D0~D7 will be

interpreted as the horizontal shift value.

X1X0=00: 0.00% (POR)

X1X0=01: -0.18%

X1X0=10: -0.22%

X1X0=11: -0.35%

X0=0: Decrease by one level

X0=1: Increase by one level

(Note: increment/decrement wraps round among the 16 contrast

levels. Start at the lowest level when POR.

X0=0: normal operation (POR)

X0=1: test mode select

(Note: Make sure to set X0=0 during application)

X0=0: External oscillator (POR)

X0=1: Internal oscillator.

For internal oscillator place a resistor between OSC1 and OSC2.

For external oscillator mode, feed clock input to OSC2.

X0=0: oscillator master disable (POR)

X0=1: oscillator master enable.

This is the master control fro oscillator circuitry. This command

should be issued after the “External / Internal Oscillator” com-

mand.

Set GDDRAM Column Address.

Use X6X5X4X3X2X1X0 as address bits.
