SYMBOL
DESCRIPTION
INT
Digital output, open drain, 5V tolerant. Interrupt output indicating mode change or command execution status. Pull high
with a 4.7k resistor.
DE
3.3V digital output. High when there is valid video data, low during horizontal and vertical blanking periods.
FIELD
3.3V digital output. For interlaced video, this output will changes states to indicate whether current field is even or odd.
Polarity is determined by configuration register.
