Help¶

Controls the behavior of the FIFO when the FIFO becomes completely filled with data. If set, the FIFO address rolls over to zero and the FIFO continues to fill with new data. If not set, then the FIFO is not updated until FIFO_DATA is read or the WRITE/READ pointer positions are changed.

Direct dependencies¶

(Includes any dependencies from ifs and menus.)
