DIGITAL_PORT_D_HOT_PLUG_INTERRUPT_DETECT_STATUS:
Project: All
Default Value: 0b AccessType: One to Clear This reflects hot plug detect status on the
digital port. Graphics software must write a one to these bits to clear the status. This bit
is used for either monitor hotplug/unplug or for notification of a sink event. When either
a long or short pulse is detected, one of these bits will set. These bits are ORed together
to go to the main ISR hotplug register bit.
