Notes:
1. The least significant bit (LSB) of write data is displayed on the first line. The most significant bit (MSB) is
displayed on the 8th raster-row.
2. The 8th raster-row is the cursor position and its display is formed by a logical OR with the cursor.
3. A set bit in the CGRAM data corresponds to display selection (lit) and 0 to non-selection (unlit).

Notes: 1. In the graphic display mode (GR = 1), graphics pattern is displayed using bitmap data set to
CGRAM as per the above table.
2. Each display character and display line are converted to 6-dot width/character and 8 dots/line,
respectively.
3. The 4th line is displayed by vertical smooth scroll operation.
