(P1–P6) that are shown in the figure. In ungated mode the VSYNC and PIXCLK signals are used, and the
HSYNC signal is ignored.

Figure 23
describes the timing parameters (t1–t14) that are shown in the figures. The values shown in timing
diagrams were tested using a worst-case core voltage of 1.1 V, slow pad voltage of 2.68 V, and fast pad
voltage of 1.65 V.
