R/W, 0
Reserved. Reserved for data expansion.
R/W, 0
DM Size 8 Kbytes. When set, causes 8 Kbytes of
data to move. Bits <3:0> must be zero if this bit is set.
R/W, 0
DM Size 4 Kbytes. When set, causes 4 Kbytes of
data to move. Bits <4; 2:0> must be zero if this bit is
set.
R/W, 0
DM Size 2 Kbytes. When set, causes 2 Kbytes of
data to move. Bits <4:3; 1:0> must be zero if this bit is
set.
R/W, 0
DM Size 1 Kbyte. When set, causes 1 Kbyte of data
to move. Bits <4:2;0> must be zero if this bit is set.
R/W, 0
DM Size 512 Bytes. When set, causes 512 bytes of
data to move. Bits <4:1> must be zero if this bit is set.
Encoding
Initialize memory at the addresses
specified by the TLDMADRA register
and the data length field to zero.
Read blocks from addresses specified
by the TLDMADRA register and the
data length field. The read causes
the blocks to become shared.
Copy data from source address speci-
fied by the TLDMADRA register and
the data length field to the addresses
specified by the TLDMADRB register
using the same offsets. This func-
tion is used to move blocks of data
from one portion of memory to an-
other.
Copy data from source address speci-
fied by TLDMADRA and the data
length field to itself. This function is
used to make a block of data visible
to the Memory Channel interface by
forcing a write of the data on the bus.
