The MegaCore function can be configured to support between 1 to 14 different modes
and each mode has a bank of registers that describe the output frame. When the
MegaCore function receives a new control packet on the Avalon-ST Video input, it
searches the mode registers for a mode that is valid and has a field width and height
that matches the width and height in the control packet. The register Video Mode
Match shows the selected mode. When found, it restarts the video output with those
format settings. If a matching mode is not found, the video output format is
unchanged and a restart does not occur.
