RAM
Specify the CG ROM to be used for display. Although internal CG ROM can generate 160
discrete character fonts (each consisting of 5 x 7 dots as shown in Section 4.4.1 “Character
Fonts (Internal CG)” on page 81), internal CG RAM may be used when different character
fonts or more characters (up to 256) are needed.
M0
Note: When the CG area is mapped in the display memory space, the memory area
Selects the CG RAM definition area where the user can define any desired character pattern.
The CG RAM code may be selected from the 64 discrete codes assigned in Section 4.4.2
“Character Codes” on page 82.
M1
Select the CG size in the Y direction for more economical use of internal CG RAM. CGs whose
sizes in the Y direction are 17 dots or more cannot be handled with the character codes of the
S1D13700. In such case, characters may be decomposed into bit images and displayed in
graphic display mode of the S1D13700.
