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 I2C 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.
