Port 2
: 8-bit open-drain bidirectional port with alternative functions.
P2.0/TPWM is the output for the 14-bit high precision PWM.
P2.1/PWM0 to P2.7/PWM6 are the outputs for the 6-bit PWMs 0 to 6.
Port 3
: 8-bit open-drain bidirectional port with alternative functions.
P3.0/ADC0 to P3.3/ADC3 are the inputs for the software ADC facility.
P3.4/PWM7 is the output for the 6-bit PWM7.

Digital ground.
Port 0
: 8-bit open-drain bidirectional port.
P0.5 and P0.6 have 10 mA current sinking capability for direct drive of LEDs.
Analog ground.
Composite video inputs; a positive-going 1 V (peak-to-peak) input is required,
connected via a 100 nF capacitor.
Video black level storage input: this pin should be connected to V
SSA
via a
100 nF capacitor.
Reference current input for analog circuits, connected to V
SSA
via a 27 k
resistor.
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.
