During the vertical shift time, the horizontal clocks are held in one state. This
bit controls whether H4 is held high or low during this time.

h4d
A “0” indicates that the signal state is low, a “1” indicates that the signal state
is high.
The phase of the falling edge of H4 can be programmed through this register.
The falling edge of H4 corresponds to the rising edge of the internally selected
clock. The phases of these clocks in shown in Figure 19, with the complement-
ed clocks being the inverse of these (i.e. the falling edge of p1 is the rising
edge of p1, etc.).
