TMDS output edge-rate control: This feature adjusts the TMDS461 TMDS output rise and fall times. There
are four settings that can be chosen. The default setting is the fastest rise and fall time; the other three
settings are slower. Slower edge transitions can potentially help the sink system (HDTV) in passing regulatory
EMI compliance.
Automatic Port Select Feature available in I2C mode
5V_PWR detect for each port connected, Hot Plug Detect (HPD) of non selected port follows 5V_PWR,
whereas HPD of selected port follows HPD_SINK.
