Note: Ts is the LCD_LSCLK period. LCD_VSYNC, LCD_HSYNC, and LCD_OE can be programmed as active high or active
low. In Figure 19, all 3 signals are active low. LCD_LSCLK can be programmed to be deactivated during the
LCD_VSYNC pulse or the LCD_OE deasserted period. In Figure 19, LCD_LSCLK is always active.
Note: XMAX is defined in number of pixels in one line.
