DC input voltage to define the output HIGH level on the RGB pins.
Pixel rate output of the BLUE colour information.
Pixel rate output of the GREEN colour information.
Pixel rate output of the RED colour information.
Video/data switch push-pull output for dot rate fast blanking.
Schmitt trigger input for a TTL level version of the horizontal sync pulse; the
polarity of this pulse is programmable by register bit TXT1.H POLARITY.
Schmitt trigger input for a TTL level version of the vertical sync pulse;
the polarity of this pulse is programmable by register bit TXT1.V POLARITY.
+5 V analog power supply.
+5 V teletext power supply.
Crystal oscillator ground.
12 MHz crystal oscillator input.
12 MHz crystal oscillator output.
If the reset input is HIGH for at least 3 machine cycles (36 oscillator periods)
while the oscillator is running, the device is reset; this pin should be
connected to V
