Composite Video Baseband Signal (CVBS) input; a positive-going 1 V
(peak-to-peak) input is required; connected via a 100 nF capacitor
sync-pulse-filter input for CVBS; this pin should be connected to V
100 nF capacitor
reference current input for analog circuits; for correct operation a 24 k resistor
should be connected to V
Frame de-interlace output synchronized with the VSYNC pulse to produce a
non-interlaced display by adjustment of the vertical deflection circuits
not available; connect this pin to V
contrast reduction: open-drain, active LOW output which allows selective contrast
reduction of the TV picture to enhance a mixed mode display
analog supply voltage (3.3 V)
Blue colour information pixel rate output
output for 14-bit high precision Pulse Width Modulator (PWM)
outputs for 6-bit PWMs 0 to 6
inputs for the software Analog-to-Digital-Converter (ADC) facility
output for 6-bit PWM7
