Notes: 1. The lower 2 bits of the character code correspond to the upper two bits of the CGRAM address
(2 bits: 4 types).
2. CGRAM address bits 0 to 2 designate the character pattern raster-row position. The 8th raster-
row is the cursor position and its display is formed by a logical OR with the cursor.
3. The upper three bits of the CGRAM data are invalid; use the lower five bits.
4. When the upper four bits (bits 7 to 4) of the character code are 0, CGRAM is selected.
Bits 3 and 2 of the character code are invalid (*). Therefore, for example, the character codes
(00)H and (08)H correspond to the same CGRAM address.
5. A set bit in the CGRAM data corresponds to display selection, and 0 to non-selection.
* Indicates no effect.
