FIFO Use Enable [3:0] (Default: 0x0)
Each channel specifies whether to use 8-double word FIFO in Dual
Address transfer. FIFUM[n] corresponds to channel n.
Refer to “8.3.8.2 Burst Transfer During Dual Address Transfer” for more
information.
Round Robin Priority (Default: 0)
Specifies the method for determining priority among channels.
1: Round Robin method. Priority of the last channel used is the lowest,
0: Fixed Priority. Priority is fixed in the order Channel 0 > Channel 1 >
Master Enable (Default: 0)
This bit enables the DMA Controller.
1: Enable
0: Disable
Note: If the entire DMA Controller is disabled, then all internal logic
and the next previous channel has the next lowest priority. Round robin
is in the order Channel 0 > Channel 1 > Channel > Channel 3.
Channel 2 > Channel 3.
including the Bus Interface Logic and State Machine are reset.
