Notes 1. The display RAM is undefined state at the AC pin.
2. The display RAM consists of 2 pages, page 0 and page 1 (common address). The page in which data is written is controlled by the
DAF bit. When set to "0", data is written into page 0, whereas when set to "1", data is written into page 1.
3. However, set "1" only when using the "FF16" blank code as the text code.
