Valid when the CTRL1 pin (pin 4) is high.
The input clock frequency in clock input
mode is either 4fsc or the dot clock
frequency.
This sets the clock polarity for system
operation when pin 2 is used as a clock
input.
The VSYNC pin (pin 21) must be tied to
ground or VDD in composite
synchronizing signal input mode.
