Open-drain, active LOW output which allows selective
contrast reduction of the TV picture to enhance a
mixed mode display.
+3.3 V analog power supply
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 triggered input TTL version of the horizontal
sync pulse. The polarity of this pulse is programmable
by register bit TXT1.H POLARITY.
Schmitt triggered input for a TTL version of the vertical
sync pulse. The polarity of this pulse is programmable
by register bit TXT1.V POLARITY.

+3.3 V core power supply
crystal oscillator ground
12 MHz crystal oscillator input
12 MHz crystal oscillator output
If the reset input is HIGH for at least 2 machine cycles
(24 oscillator periods) while the oscillator is running,
the device is reset. This pin should be connected to

+3.3 V periphery power supply
Port 1. 8-bit programmable bidirectional port with
alternative functions.
P1.0/INT1 is external interrupt 1 which can be
triggered on the rising and falling edge of the pulse.
P1.1/T0 is the Counter/Timer 0. P1.2/INT0 is external
interrupt 0. P1.3/T1 is the Counter/Timer 1.
P1.6/SCL0 is the serial clock input for the I
P1.7/SDA0 is the serial data port for the I
P1.4/SCL1 is the serial clock input for the I
P1.5/SDA1 is the serial data port for the I
