LogiCORE IP DisplayPort v3.2 - Why does the DisplayPort Sink IIC Controller hold the SCL line in some cases when large amounts of noise are introduced into it via the AUX channel input?

描述

Why does the DisplayPort Sink IIC Controller hold the SCL line in some cases when large amounts of noise are introduced into it via the AUX channel input?

In some cases, it has been observed that noise introduced through the DisplayPort cable can cause the DisplayPort Sink IIC Controller to become stuck and the SCL to be held low.

解决方案

An automatic reset has been added to the DisplayPort Sink IIC Controller state machine in case this condition is observed.

This fix will be available in the next version of the LogiCORE DisplayPort core.

If you need a patch for the DisplayPort v3.2, please contact Xilinx Technical Support.
