DESCRIPTION
A test pin. Set open or to L level in the normal mode.
An input pin to control electronic exposure using EEUD
(pin 35) and EENR (pin 36).
L level
: Electronic exposure is stopped.
H level or open
: Electronic exposure is operated.
An output pin for window pulse.

Window pulse output
WIND1 : When connected to EEST (pin 2), the
operation of electronic exposure can be
stopped at the upper side of monitor.
WIND2 : A pulse that picks out the center of CCD output.
At this time, set H level or open at EEST (pin 2).
As the output circuit of WIND is N-ch open
drain, connect to V
DD
with R (≥ 47 k$).
An input pin for resetting internal vertical counter.
The input pulse is VSYNC (negative polarity).
A test pin. Set open or to L level in the normal mode.
A test pin. Set open or to L level in the normal mode.
A grounding pin.
Supply of +5 V power.
