Master/slave operation selection in other modes than ITU-R BT.656. Internal
pull-down. "1" : Master / "0" : Slave
Only slave mode is selected in ITU-R BT.656 mode (input of "1" is invalid)
GENLOCK signal I/O pin.
Composite sync output pin.
Vertical sync input/output pin (output mode in master mode/input mode in
slave mode)
Horizontal signal input/output pin (output mode in master mode/input mode
in slave mode)
Composite blank signal input pin.
3.3 V digital power supply.
Digital GND.
8-bit digital image chrominance signal data input pins at pixel rate
operation. Level conforms to ITU-R BT.601. R signal input pins in RGB input
mode. CD7 is MSB. Fixed to "0" when not used.
8-bit digital image data input pins at double pixel rate operation. 8-bit digital
luminance signal data input pins at pixel rate operation. Level conforms to
ITU-R BT.601. G signal input pins in RGB input mode. YD7 is MSB.
Digital GND
3.3 V digital power supply
B signal input pins in RGB input mode. Fixed to "0" when not used.
Field information output pin (Odd Field : "1", Even Field : "0") (Polarity can
be changed by the internal register.)
System reset pin.
Input pin for testing. Normally fixed to "0". Internal pull-down. The user
cannot use this pin.
Clock input pin.
