When the HDMI transmitter does not have the capability of detecting the receiver termination, using the HPD
signal as a reference for sensing port selections is the only possible method. External control logic for switching
the connections of the HPD signals between the HPD pins of the TMDS351 and the 5-V signal from the source
provides a good solution.
E-EDID Reading Configurations in Standby Mode
When the TMDS351 is in standby mode operation, S1 = H and S2 = L, all sources can read their E-EDID
memories simultaneously with all HPD pins following HPD_SINK in logic-high. HPD_SINK input low will prevent
E-EDID reading in standby mode operation.
