De-interlace output synchronised with the VSYNC pulse to produce a non-interlaced
display by adjustment of the vertical deflection circuits.
Internally connected; this pin should be connected to digital ground.
Open-drain, active LOW output which allows selective contrast reduction of the TV
picture to enhance a mixed mode display.
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 display power supply.
+5 V display 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
DDM

P1.0/INT1 is external interrupt 1, can be triggered on the rising/falling edge of pulse.
P1.1/T0 is the counter/timer 0.
P1.2/INT0 is the external interrupt 0.
P1.3/T1 is the counter/timer 1.
P1.7/SDA is the serial data port for the I
