3. LCD Interface
3.1
LCD driving method
3.1.1 LCD driving mode
The ML87V3104 is suitable for various types of LCD panels, and allows the LCD driving mode to be selected by
setting the control registers.
The number of valid data bits in the LCD interface varies depending on the driving mode. The output data signals
that are not used will be maintained in the high-impedance state. Further, there are some restrictions on the
selection of the display memory data width (bits per pixel) depending on the driving mode. (Table F3.1)
Control registers:
LCDMOD [#00h; bit7-4]:
LCD panel operation mode
LCDDAT [#00h; bit3-0]:
LCD panel interface data width
