Remark4-1】When it’s ”H”, EXTCOMIN signal is enable. And when it’s ”L” ,sirial input flag is enable.

【

Remark4-1】When it’s ”H”, EXTCOMIN signal is enable. And when it’s ”L” ,sirial input flag is enable.

“H”mode; connect the EXTMODE toVDD, ”L” mode; connect the EXTMODE to VSS.

【

Remark4-2】The display ON/OFF signal is only for display. Data in the memory will be saved at the time of ON/OFF.

When it’s ”H”, data in the memory will display, when it’s ”L”, white color will diaplay and data in the memory will be

saved.
