bits 0 to 4 is set to "1", the corresponding display location will light up regardless of the
cursor position.
6. When the Character Code Bits 4 to 7 are set to "0", then the CGRAM Character
Pattern is selected. It must be noted that Character Code Bit 3 is not relevant and will not
have any effect on the character display. Because of this, the first Character Pattern shown
above ( R ) can be displayed when the Character Code is 00H or 08H.

2. The character pattern row positions correspond to the CGRAM data bits -- 0 to 4, where
bit 4 is in the left position.
3. Character Code Bits 1 and 2 correspond to the CGRAM Address Bits -- 4 and 5
respectively (2 bits : 4 types)
4. If the CGRAM Data is set to "1", then the selection is displayed. If the CGRAM is set to
"0", there no selection is made.
5. The CGRAM Address Bits 0 to 3 are used to define the character pattern line position. The
11th line is the cursor position and its display is formed by the logical OR with the cursor.
