Notes: 1. CGRAM is selected when the upper 9 bits (C3 to C11) of the full size character codes are 0. In
this case, the lower 3 bits (C0 to C2) of the character code correspond to bits 5 to 7 (A5 to A7) (3
bits: 8 types) in the CGRAM address.
2. CGRAM address bits 1 to 4 (A1 to A4) designate the character pattern line position. The 12th
line is the cursor position and its display is formed by a logical OR with the cursor.
3. CGRAM address 0 (A0) corresponds to the left-half and right-half of a full-size character pattern.
4. The character data is stored with the rightmost character element in bit 0 (LSB), as shown in the
table above. Pattern produced by bits 0 to 5 is displayed and 13 raster-rows are displayed
together. Thus, an arbitrary character pattern consisting of 12
×
13 dots can be displayed.
5. A set bit in the CGRAM data corresponds to display selection, and 0 to non-selection.
6. The upper two bits (AA) of CGRAM data indicate the display attribute for the lower 6-bit pattern.
In this case, display attributes specified for the DDRAM during full-size character display is
disabled. When these upper two bits are 00, the CGRAM pattern is simply displayed as set;
when 01, the pattern reverses (black/white), when 10, the pattern blinks; and when 11, the
pattern reverses and blinks.
