Description
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 “14.3.8.2 Burst Transfer During Dual Address Transfer” for more
information.
Round Robin Priority (Default: 0)
Specifies the method for determining priority among channels.
1:
lowest, and the next previous channel has the next lowest priority. Round
robin is in the order Channel 0 > Channel 1 > Channel > Channel 3.
0:
> Channel 2 > Channel 3.
Master Enable (Default: 0)
This bit enables the DMA Controller.
1: Enable
0: Disable
Note:
including the Bus Interface Logic and State Machine are reset.
Round Robin method. Priority of the last channel used is the
Fixed Priority. Priority is fixed in the order Channel 0 > Channel 1
If the entire DMA Controller is disabled, then all internal logic
