Programming character patterns
This section explains the correspondence between addresses and data used to program character
patterns in EPROM. The HD66710 character generator ROM can generate 240 5
×
8 dot character
patterns.
Character patterns
EPROM address data and character pattern data correspond with each other to form a 5
×
8 dot
character pattern (Table 4).

Notes: 1. EPROM addresses A11 to A4 correspond to a character code.
2. EPROM addresses A2 to A0 specify a line position of the character pattern. EPROM address
A3 should be set to 0.
3. EPROM data O4 to O0 correspond to character pattern data.
4. Area which are lit (indicated by shading) are stored as 1, and unlit are as 0.
5. The eighth line is also stored in the CGROM, and should also be programmed. If the eighth line
is used for a cursor, this data should all be set to zero.
6. EPROM data bits O7 to O5 are invalid. 0 should be written in all bits.
