A grounding pin.
An input pin to control internal vertical clock for long
shutter speed.
H level or open
: VD
L level
: VD is masked by the pulse which
is latched at the rising edge of VD.
It's necessary to be set SMD = high and number of the
fields data n ≥ 2 in serial data control at VCON operation.
An input pin for reference clock oscillation.
The frequency is 35.874 MHz.
