NOTE
• Ts is the GLCD_LSCLK period. GLCD_VSYNC,
GLCD_HSYNC, and GLCD_OE can be programmed as
active high or active low. In the preceding figure, all 3
signals are active low. GLCD_LSCLK can be programmed
to be deactivated during the GLCD_VSYNC pulse or the
GLCD_OE deasserted period. In the preceding figure,
GLCD_LSCLK is always active.
• XMAX is defined in number of pixels in one line.
