Type
Default Description PowerWell ResetSignal
Assigns a hardware
handshaking interface (0-1)
to the channel destination if
the CFG0_L.HS_SEL_DST
field is 0; otherwise, this field
is ignored. The channel can
then communicate with the
destination peripheral
connected to that interface
through the assigned
hardware handshaking
interface. NOTE: For correct
DMA operation, only one
peripheral (source or
destination) should be
assigned to the same
handshaking interface.
10:7 RW 4'h0 Source hardware interface
(SRC_PER)
Assigns a hardware
handshaking interface (0-1)
to the channel source if the
CFG0_L.HS_SEL_SRC field is
0; otherwise, this field is
ignored. The channel can
then communicate with the
source peripheral connected
to that interface through the
assigned hardware
handshaking interface. NOTE:
For correct DMA operation,
only one peripheral (source
or destination) should be
assigned to the same
handshaking interface.
6 RW 1'b0 Source Status Update
Enable (SS_UPD_EN)
Source status information is
fetched only from the
location pointed to by the
SSTATAR0 register, stored in
the SSTAT0 register and
written out to the SSTAT0
location of the LLI if this field
is high
5 RW 1'b0 Destination Status Update
Enable (DS_UPD_EN)
