14.1.5 HDMI Interrupts Validity Checking Process

All HDMI interrupts have a set of conditions that must be taken into account for validation in the
display firmware. When the ADV7604 interrupts the display controller for an HDMI interrupt, it
must check that all validity conditions for that interrupt are met before processing that interrupt.
For simplicity, HDMI interrupts can be subdivided into three groups, as listed in
14.1.5.1, 14.1.5.2 and
Rev. F August 2010
