Type
Default Description PowerWell ResetSignal
10:9 RW 2'b0 Source Address Increment
(SINC)
Indicates whether to
increment or decrement the
source address on every
source transfer. If the device
is fetching data from a source
peripheral FIFO with a fixed
address,
then set this field to No
change.
00 = Increment
01 = Decrement
1x = No change
NOTE: Incrementing or
decrementing is done for
alignment to the next
SRC_TR_WIDTH boundary.
8:7 RW 2'b0 Destination Address
Increment (DINC)
Indicates whether to
increment or decrement the
destination address on every
destination transfer. If your
device is writing data to a
destination peripheral FIFO
with a
fixed address, then set this
field to No change
00 = Increment
01 = Decrement
1x = No change
NOTE: Incrementing or
decrementing is done for
alignment to the next
DST_TR_WIDTH boundary.
6:4 RW 3'b000 Source transfer width
