R/W Module Interface Type Select
R/W Set the LCD panel type and data bus width to be
R/W output to the LCD panel. There are three LCD panel
R/W types: STN, DSTN, and TFT. There are four data bus
R/W widths for output to the LCD panel: 4, 8, 12, and 16
R/W bits. When the required data bus width for a TFT
panel is 16 bits or more, connect the LCDC and LCD
panel according to the data bus size of the LCD
panel. Unlike in a TFT panel, in an STN or DSTN
panel, the data bus width setting does not have a 1:1
correspondence with the number of display colors
and display resolution, e.g., an 8-bit data bus can be
used for 16 bpp, and a 12-bit data bus can be used
for 4 bpp. This is because the number of display
colors in an STN or DSTN panel is determined by
how data is placed on the bus, and not by the
number of bits. For data specifications for an STN or
DSTN panel, see the specifications of the LCD panel
used. The output data bus width should be set
according to the mechanical interface specifications
of the LCD panel.
If an STN or DSTN panel is selected, display control
is performed using a 24-bit space-modulation FRC
consisting of the 8-bit R, G, and B included in the
LCDC, regardless of the color and gradation settings.
Accordingly, the color and gradation specified by
DSPCOLOR is selected from 16 million colors in an
STN or DSTN panel. If a palette is used, the color
specified in the palette is displayed.
