TMDS181: Signal detect register

Toshi

Part Number: TMDS181

Hi, TI,

I'd like to confirm the "signal detect circuit". I can detect a input signal is presented or not by the HOT PLUG DETECT PINS,

Well, does the device have a register bit for the detection ?

Hi Toshi,

The signal detect circuit, looks for a valid clock from HDMI source
HPD_SNK senses if there is an HDMI display connected.

There are a couple debug register you can use to detect HPD_SNK and signal detect status, could you elaborate what you are trying to do?

Moises, thanks. I only want to know ; Is a Input signal (Valid TMDS clock) available, or not available ?
I guess, If I can get a status of "The signal detect circuit" , It's enough.
