The subsystem supports the Hot Plug Detect (HPD) feature, which is a communication mechanism between the HDMI source and HDMI sink devices. For example, when an HDMI cable is inserted between the HDMI source and HDMI sink devices, the cable-detect signal is asserted. The subsystem then outputs a hpd signal, which triggers the start of a communication between the source device and sink device.
