A change in the RX reference clock signifies a video format change, which triggers a series of interrupts until the GT RX attains the RX Reset Done status.

There are several API callback hooks that the Video PHY Controller core executes throughout the HDMI RX operation. If necessary, these callbacks are available for inserting or adding more function calls on top of what is in the software application.
