CG RAM address
(3) Method of determining the CG address
The addition shown below is performed to generate CG RAM addresses. Therefore, note that CG RAM
data is not mapped from addresses set in the SAG register to the VRAM space, but are mapped based on
the SAG + character code + row select address.
1When number of lines that comprise the character font is equal to or less than 8 (M2 = 0, M1 = 0)
2When number of lines that comprise the character font is from 9 to 16, including both ends (M2 = 1, M1
3When M1 = 1
Note: Up to 64 characters can be used in one bank when used in combination with CG ROM.
Note: Only the addressing above is supported.
Note: 1. Line count l ... when character font consists of 8 lines or less
For the character codes defined in CG RAM2, the S1D13700 automatically changes the D6 bit in the
character code from 1 to 0. This ensures that the data storage area in CG RAM corresponds to
= 0)
When using only CG RAM, up to 256 characters can be used in one bank. Also note that
the relationship between CG patterns and character codes changes when banks are
switched over.
Line count 2 ... when character font consists of 9 lines or more
