Comment

1 1 * A4 A3 A2 A1 A0 Sets address pointer value

A0, A1, A2, A3 A4: address pointer value

(binary)

Sets on/off of LCD panel

1 0 0 * 1 0 0 DI

Panel is on when DI = "1"

Panel is off when DI = "0"

Sets blink in 5 dot units

0 * * * 0 0 CB * Blink starts in 5 dot units when CB = "1"

Blink is cleared when CB = "0"

Sets writing method to arbitrator blink RAM

Sets blink pattern of characters

1 0 0 * 0 0 1 BP When BP = 1, all off ´ character blink

When BP = 0, all on ´ character blink

1 0 0 * 1 * 1 * Increments address pointer value by 1

1 0 1 1 * * I1 I0 Sets additional function of AINC command

Set SO pin

1 0 0 * 0 1 1 S SO pin is a CMOS output when S = "1"

SO pin is in a high impedance state when S = "0"

The commands listed above requires the wait time (21 ¥ 1/fOSC).

The address pointer value is incremented by 1 when CG ROM code data, arbitrator display data

and arbitrator blink data are input and when AINC and CHB commands are executed.
