X42A-A-002-04
Note
The internal character generator is recommended for minimum system configurations
containing a S1D13700F01, display RAM, LCD panel, single-chip microprocessor and
power supply. Since the internal character generator uses a CMOS mask ROM, it is also
recommended for low-power applications.
• 5 x 7 pixel font (See Section 16, “Internal Character Generator Font” on page 125)
• 160 JIS standard characters
• Can be mixed with character generator RAM (maximum of 64 CGRAM characters)
• Can be automatically spaced out up to 8 x 16 pixels
The character generator RAM can be used for storing graphics characters. The character
generator RAM can be mapped to any display memory location by the microprocessor,
allowing effective usage of unused address space.
• Up to 8 x 8 pixel characters when REG[00h] bit 2 = 0 and 8 x 16 characters when
• Can be mapped anywhere in display memory address space if used with the character
REG[00h] bit 2 = 1
generator ROM (REG[00h] bit 0 = 0)
If the CGRAM is used (includes CGRAM1 and CGRAM2), only 1 bpp is supported.
