pin to GND is used to control full scale
amplitudes of the video signal.
35 S C R E S E T / This pin can be configured as an input by
R T C setting MR22 and MR21 of mode register
2. It can be configured as a subcarrier
reset pin, in which case a high to low
transition on this pin will reset the
subcarrier to field 0. Alternately it may be
configured as a real time control (RTC)
input.
36 TTX REQ Teletext data request signal
Defaults to GND when teletext not selected
(enables backward compatibility to
ADV7175/ADV7176).
37 TTX V Teletext data
