The frequency setting of the interface clock, LSCLK, is determined by the panel specifications. To avoid flicker on
the screen set LSCLK to be within the panel specifications. Use an oscilloscope to probe LSCLK to ensure that the
clock frequency is set correctly. If flicker problems occur, visually inspect the interface clock by probing even
when the clock settings have been programmed correctly.
