(c) HLIM (high speed shutter limiter)

By combining the HLIM1 pin (Pin 62) and the HLIM2 pin (Pin 63), the maximum shutter speed can be

changed.

(d) Power on reset

During electronic iris mode (IRENB = high), the initial settings for the iris are made in the instant the

POWER pin (Pin 54) switches from low to high.

The initial setting shutter speed is 1/1000 (s).

By applying the circuit shown below, the shutter speed can be initialized when the power is turned on.
