Lock input of FIFO and empty FIFO (only in write mode). Unlock FIFO and start next transfer
using the base address at the detection of BOF.
Restart immediately at base address.
Lock input of FIFO, empty FIFO (only in write mode) and then reset TR_E bit. The next transfer
starts with BOF using the corresponding base address, if the TR_E bit is set again. This setting
is useful for single-shot, that means transferring only one frame of a video stream. Therefore
the protection address has to be the same as the address of the last pixel of the field.
