Supported Boards:
▪ MX-HDMI-OB; MX-DVI-HDCP-OB; MX-HDMI-TP-OB; CPU-OB (Preview output)
Description: The system continuously measures the parameters of the signals. The answer consists of 16
data bytes and every data byte is represented as a two-digit hexadecimal number. The parameters could be
useful for advanced debugging processes.
