VD/VAF/FIELD timing signal output
- selection of VD/VAF signal output and FIELD signal output is determined by
register setting
P
I/O _{- in camera I/F mode, VAF signal is always output}
- output state is controlled by combinations of RSTN/PDN/OE pin settings (note 1)
- this pin is used as an I/O pin in test mode

Valid video interval
- output state is controlled by combinations of RSTN/PDN/OE pin settings (note 1)
Indicates synchronization condition with input signal
- L : synchronized with input signal
P
O _{- H : no signal input or out of synchronization}
- output state is controlled by combinations of RSTN/PDN/OE pin settings (note 1

Reference current setting
- connect this pin to analog ground through a 6.8kΩ resistor (≤1% accuracy)
A
I/O _{- this pin goes to high-Z in power-down mode (no high-Z test is performed in}
production test)
Internal negative reference voltage for ADC
- connect this pin to analog ground through a 0.1uF or larger capacitor
A
I/O - this pin may go to high-Z in power-down mode (no high-Z test is performed in
production test)
- do not use this as a reference voltage source for external circuitry
Internal positive reference voltage for ADC
- connect this pin to analog ground through a 0.1uF or larger capacitor
A
I/O - there is a case when this pin becomes Hi-Z output at power-down ( no Hi-Z test is
performed in mass-production test )
- do not use this pin as a reference voltage source for external circuit.
Internal common voltage for AD converter
- connect this pin to analog ground via a 0.1 uF or larger capacitor.
A
I/O - there is case when this pin becomes Hi-Z output at power-down (no Hi-Z test is
