Note: Ts is the LCD_LSCLK period while Tpix is the pixel clock period. LCD_VSYNC, LCD_HSYNC, and
LCD_LSCLK can be programmed as active high or active low. In Figure 21, all these 3 signals are active
high. When it is in CSTN mode or monochrome mode with bus width = 1, T3 = Tpix = Ts. When it is in
monochrome mode with bus width = 2, 4 and 8, T3 = 1, 2 and 4 Tpix respectively.
