DISPB_D3_DRDY acts like an output enable signal to the CRT display. This output enables the
data to be shifted onto the display. When disabled, the data is invalid and the trace is off.

Figure 46 depicts the horizontal timing (timing of one line), including both the horizontal sync pulse and
the data. All figure parameters shown are programmable. The timing images correspond to inverse polarity
of the DISPB_D3_CLK signal and active-low polarity of the DISPB_D3_HSYNC, DISPB_D3_VSYNC
and DISPB_D3_DRDY signals.

Figure 47 depicts the vertical timing (timing of one frame). All figure parameters shown are
programmable.
