Section 37 LCD Controller (LCDC)
(TFT module)
The table above shows the states of the power supply, display data, and timing signals for the
typical LCD module in its active and stopped states. Some of the supply voltages described may
not be necessary, because some modules internally generate the power supply required for high-
voltage systems from the logic-level power-supply voltage.
Notes on display-off mode (LCDC stopped):
If LCD module power-supply control-sequence processing is in use by the LCDC or the supply of
power is cut off while the LCDC is in its display-on mode, normal operation is not guaranteed. In
the worst case, the connected LCD module may be damaged.
37.4.7
Operation in hardware-rotation mode is described below. Hardware-rotation mode can be thought
of as using a landscape-format LCD panel instead of a portrait-format LCD panel by placing the
landscape-format LCD panel as if it were a portrait-format panel. Whether the panel is intended
for use in landscape or portrait format is thus no problem. The panel must, however, be within 320
pixels wide.
When making settings for hardware rotation, the following five differences from the setting for no
hardware rotation must be noted. (The following example is for a display at 8 bpp. At 16 bpp, the
amount of memory per dot will be doubled. The image size and register values used for rotation
will thus be different.)
1. The image data must be prepared for display in the rotated panel. (If 240 × 320 pixels will be
2. The register settings for the address of the image data must be changed (LDSARU and
