This DDC12AB Interface module is used by the digital monitor to show
its identification information to the video controller. It contains DDC1
hardware and a two-wire, bidirectional serial bus which is fully
compatible with multi-master IIC bus protocol to support DDC2AB
interface.
This module not only can be applied in internal communications, but can
also be used as a typical command reception serial bus for factory setup
and alignment purposes. It also provides the flexibility of hooking
additional devices to an existing system for future expansion without
adding extra hardware.
