4.5 Character Generator ROM (CGROM)
The Character Generator ROM (CGROM) generates 5 x 7 dot or 5 x 10 dot character
patterns from 8-bit character codes. It can generate up to 192 types of 5x7 dot character
patterns and 32 types of 5x10 dot character patterns. Table 4.3 shows the relation
between character codes and character patterns of the standard character font.
4.6 Character Generator RAM (CGRAM)
The CGRAM is a 64 x 8 bit RAM in which the user can program custom character patterns.
With 5 x 7 dots, 8 types of character patterns can be written and with 5 x 10 dots 4 types
of character patterns can be written. To write previously programmed characters from the
CGRAM to the DDRAM, character codes 00H through 07H are used. (See character font
Table 4.3). Unused CGRAM locations can be used for general purpose RAM.
The relationship between CGRAM address and data and the displayed character is shown
in Tables 4.2
To program a 5 x 7 character pattern into the CGRAM location (for example, character
code 01H), the following steps should be taken.
A. Use the “Set CGRAM address” command to position the CGRAM pointer to the 1st row
of character code 01H (CGRAM address=48H).
B. Use the “Write Data to CG or DDRAM” Command to write the top row of the custom
character (Only lower 5-bit of character pattern data is valid).
C. The CGRAM address is automatically increased if the I/D bit is set in the “Entry Mode
Set” command. When this is the case, return to step B until all rows of the character are
written.
D. After writing all 7 rows of data, use the “Set DDRAM address” command to return the
address counter to a DDRAM location.
E. To display the custom character written above, use the “Write Data to CG or DDRAM”
command with the data being 01H to display the character in the DDRAM address.
