The polarity of the coast signal can be set through the coast
polarity register (Register 0x18, Bits[6:5]). In addition, the
polarity of the Hsync signal can be set through the Hsync polarity
register (Register 0x12, Bits[5:4]). For both Hsync and coast,
a value of 1 is active high. The internal coast function is driven
off the Vsync signal, which is typically a time when Hsync
signals can be disrupted with extra equalization pulses.
