6. Repeat steps
This procedure ensures that the update is performed exactly once per frame and that
the MegaCore function is not processing data while the update is performed. When
using MegaCore functions which double-buffer control data, such as the Alpha
Blending Mixer and Scaler, a more simple process may be sufficient:
1. Set the Go bit to zero. This causes the MegaCore function to stop if it gets to the end
2. Update the control data.
3. Set the Go bit to one.
The reading on non-video packets is performed by handling any packet until one
arrives with type 0. This means that when the Go bit is checked, the non-video type
has been taken out of the stream but the video is retained.

Table 4–10. Avalon-MM Slave Interface Signal Types
Clock and reset signal types are not included. The Video and Image Processing Suite
does not support Avalon-MM interfaces in multiple clock domains. Instead, the
Avalon-MM slave interfaces must operate synchronously to the main clock and reset
signals of the MegaCore function. The Avalon-MM slave interfaces must operate
synchronously to this clock.

The next time a new frame is started after the Go bit is set to one, the new control
data is loaded into the MegaCore function.
