Character code bits 0 to 2 correspond to CGRAM address bits 3 to 5 (3 bits: 8 types).
CGRAM address bits 0 to 2 designate the character pattern line position. The 8th line is the cursor position
and its display is formed by a logical OR with the cursor. Maintain the 8th line data, corresponding to the
cursor display position, at 0 as the cursor display. If the 8th line data is 1, 1 bits will light up the 8th line
regardless of the cursor presence.
Character pattern row positions correspond to CGRAM data bits 0 to 4 (bit 4 being at the left).
As shown Table 5, CGRAM character patterns are selected when character code bits 4 to 7 are all 0.
However, since character code bit 3 has no effect, the R display example above can be selected by either
character code 00H or 08H.
“1” for CGRAM data corresponds to display selection and “0” to non-selection,“-“ Indicates no effect.
Different OPR1/2 ITO option can select different CGRAM size.
