Active-low reset. RESETB can be used only when PDN = 1. When RESETB is pulled low, it
resets all the registers and restarts the internal microprocessor.

C (sampled during reset). A pullup or pulldown resistor is
needed (>1 kΩ) to program the terminal to the desired address.
1 = Address is BAh
0 = Address is B8h
YOUT7: Most significant bit (MSB) of ITU-R BT.656 output/YCbCr 4:2:2 output
