The polarity of the coast signal may be set through the coast
polarity register (Register 0x18, Bits[6:5]). Also, 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

Vsync signal, which is typically a time when Hsync signals may
be disrupted with extra equalization pulses.
