AGCEN = 1 enables the Auto Gain Control. AGCEN = 0 disables it.
I
This pin setting is effective when pin IICB = 1. (Not used)
Frame exposure control input, effective in progressive scan only.
I
The positive width of FREX defines the exposure time. (Not used)
– Internal voltage reference. Requires an 0.1uF decoupling capacitor to ground.
– Analog ground connections.
– Analog power (+5V) pin.
I PWDN = 1 puts chip in power down (sleep) mode.
– Internal voltage reference. Requires an 0.1uF decoupling capacitor to ground.
– Internal voltage reference. Requires an 0.1uF decoupling capacitor to ground.
IICB = 1 selects the power-up method of programming the internal functions.
I IICB = 0 selects the I
can only be changed by a new power-up or reset sequence. (Not used)
O Video test output (NTSC).
– Analog power (+5V) pin.
– Analog ground connection.
