If the destination peripheral is memory, then this bit is ignored.
• FIFO_EMPTY
Indicates if there is data left in the channel's FIFO. Can be used in conjunction with CFGx.CH_SUSP to cleanly disable a
channel.
• CH_SUSP: Channel Suspend
Suspends all DMA data transfers from the source until this bit is cleared. There is no guarantee that the current transaction
will complete. Can also be used in conjunction with CFGx.FIFO_EMPTY to cleanly disable a channel without losing any
data.
• CH_PRIOR: Channel priority
A priority of 7 is the highest priority, and 0 is the lowest. This field must be programmed within the following range [0, x-1].
32072G–11/2011
0 = Hardware handshaking interface. Software-initiated transaction requests are ignored.
1 = Software handshaking interface. Hardware Initiated transaction requests are ignored.
1 = Channel's FIFO empty
0 = Channel's FIFO not empty
0 = Not Suspended.
1 = Suspend. Suspend DMA transfer from the source.
A programmed value outside this range causes erroneous behavior.
