I am working on an issue with the ADV7604. With an HDMI signal as input, the 7604 HDMI receiver status bits indicate the receiver is working, however, the CP_LOCK_xx signal does not go active. The hardware manual has no background info on the generation of the CP_LOCK_xx and CP_UNLOCK_xx signals as well as some of the other status signals. Is there more info available about these signals and how they are generated?
thank you,
