* : “Don’t care”

When the start address of negative display is set on, it is set by this command.

The lower 4 bits of

address should be set first and then upper 3 bits are set later.

The possible range is LS=00H~4FH .

The other values are forbidden.

Please set the value under the condition, LS

≤LE.

When the end address of negative display is set on, it is set by this command.

The lower 4 bits of

address should be set first and then upper 3 bits are set later.

The possible range is LS=00H~4FH . The other values are forbidden. Please set the value under the

condition, LS

LREV

( reset :{PSC, BT, LREV}=0H, read address :8H)

* : “Don’t care”

Setting the status of line inversion display tone.

LREV command : line inversion display ON/OFF setting.

LREV=”0”: normal display

LREV=”1”: line inversion display ON.

The area specified by line inversion start/stop address is

blinked.

The blink type display is controlled by BT command.

When line inversion display is ON(LREV=”1”), line inversion start address(LSi) and line inversion stop

address(LEi) should be set as following condition.

LSi

≤ LEi - (1)

And following condition is forbidden.

LEi < LSi

- (2)
