Programming character patterns
This section explains the correspondence between addresses and data used to program character patterns
in EPROM. The HD44780U character generator ROM can generate 208 5
× 8 dot character patterns and
32 5
× 10 dot character patterns for a total of 240 different character patterns.
Character patterns
EPROM address data and character pattern data correspond with each other to form a 5
× 8 or 5 ×
10 dot character pattern (Tables 2 and 3).

Notes: 1. EPROM addresses A11 to A4 correspond to a character code.
2. EPROM addresses A3 to A0 specify a line position of the character pattern.
3. EPROM data O4 to O0 correspond to character pattern data.
4. EPROM data O5 to O7 must be specified as 0.
5. A lit display position (black) corresponds to a 1.
6. Line 9 and the following lines must be blanked with 0s for a 5
× 8 dot character fonts.
