This is the mode in which the CORAL internal bus is used to transfer the display list stored in the graphics
memory to the FIFO interface.
During transfer of the local display list, the host bus can be used for CPU read/write.
How to transfer list: Store the display list in the local memory of CORAL, set the transfer source local
address (LSA) and the transfer count (LCO), and then issue a request (LREQ). Whether or not the local
display list is currently being transferred is checked using the local transfer status register (LSTA).
