The following table gives a more detailed summary of how the signals are used in each mode. These
features are also discussed in the functional description section.

FunctionModeTypeSignal
This signal functions as a frame clock the LCD uses to signal the start of a
new frame of pixels. This signal is also used by TFT displays as the vertical
synchronization signal.
Raster Mode
Output
LCDFP
(VSYNC)
This signal functions as an Address Latch Enable (ALE)LIDD Mode
This signal functions as a line clock the LCD uses to signal the end of a line
of pixels. This signal is also used by TFT displays as the horizontal
synchronization signal.
Raster Mode
Output
LCDLP
(HSYNC)
This signal functions as a write strobe or direction bit depending on the
interface mode.
