Hotplug Detect Logic
The CM2030 ensures that the local ASIC will properly
detect an HDMI compliant Sink. The current sink main-
tains a local logic “low” when no system is connected.
A valid pullup on the HDMI connector pin will overdrive
the internal pulldown and deliver a logic “high” to the
local ASIC.
