Luminance signal input.
Clamped to 4.8V at the burst timing.
Sand castle pulse output. The 0 to 5V
BGP pulse, the phase of which is
controlled through the bus, is
superimposed with the 0 to 2V H and
VBLK pulse for output.
SECAM decoder interface. This pin
serves as both a 4.43MHz output and as
a SECAM identification input/output pin.
