Dithering Algorithm for Color Mode (Continued)
Signal
…
The FIFO, Serializer, Palette and Dithering modules process one pixel at a time in monochrome
mode and three sub-pixels at a time in color mode (R,G,B components). This module packs the
data according to the output interface. This interface can be programmed in the DISTYPE,
SCANMOD, and IFWIDTH fields of the LCDCON2 register.
The DISTYPE field selects between TFT, STN monochrome and STN color display. The SCAN-
MODE field selects between single and dual scan modes; in TFT mode, only single scan is
supported. The IFWIDTH field configures the width of the interface in STN mode: 4-bit (in single
scan mode only), 8-bit and 16-bit (in dual scan mode only).
For a more detailed description of the fields, see
page
For a more detailed description of the LCD Interface, see
The time generator block generates the control signals LCDDOTCK, LCDHSYNC, LCDVSYNC,
LCDDEN, used by the LCD module. This block is programmable in order to support different
types of LCD modules and obtain the output clock signals, which are derived from the LCDC
Core clock.
The LCDDOTCK signal is used to clock the data into the LCD drivers' shift register. The data is
sent through LCDD[23:0] synchronized by default with LCDDOTCK falling edge (rising edge can
be selected). The CLKVAL field of LCDCON1 register controls the rate of this signal. The divisor
can also be bypassed with the BYPASS bit in the LCDCON1 register. In this case, the rate of
LCDDOTCK is equal to the frequency of the LCDC Core clock. The minimum period of the LCD-
DOTCK signal depends on the configuration. This information can be found in
The LCDDOTCK signal has two different timings that are selected with the CLKMOD field of the
LCDCON2 register:
• Always Active (used with TFT LCD Modules)
• Active only when data is available (used with STN LCD Modules)
