Display Data Channel Interfaces (DDC)
11.1
Introduction
The DDC (Display Data Channel) bus interfaces are mainly used by the monitor to identify itself to
the video controller, by the monitor manufacturer to perform factory alignment, and by the user to
adjust the monitor’s parameters. Both DDC interfaces consist of:
● A fully hardware-implemented interface, supporting DDC2B (VESA specification 3.0
compliant). It accesses the ST7 on-chip memory directly through a built-in DMA engine.
● A second interface, supporting the slave IC functions for handling DDC/CI mode (DDC2Bi),
factory alignment, HDCP, Enhanced DDC (EDDC) or other addresses by software.
Each DDC interface has its own dedicated DMA area in RAM. In the event of concurrent DMA
accesses, the DDC A cell has priority over the DDC B cell.
11.2
DDC Interface Features
11.2.1 Hardware DDC2B Interface Features
● Full hardware support for DDC2B communications (VESA specification version 3)
● Hardware detection of DDC2B addresses A0h/A1h

● Support for error recovery mechanism
● Detection of misplaced Start and Stop conditions
● Random and Sequential IC byte read modes
● DMA transfer from any memory location and to RAM
● Automatic memory address increment
● End of data downloading flag, end of communication flag and interrupt capability
