5.17 Descriptor 4 (DES4)
This section explains details of Descriptor 4 (DES4).
DES4 Descriptor configuration
Address: DESTP + DESP + 0x10 (ORL[2:0] = xx1)
bit
31
0
Field
DES4[31:0]
C attribute
R/W
D attribute
R
DES4 Descriptor function
bit[31:0] DES4[31:0] (Descriptor 4)
DES4 sets the value to be loaded to DES1 (number of transfers) in OuterReload. Set DES4 to the same
value as DES1 under the same configuration. The DSTC does not modify the value of this area.
5.18 Descriptor 5 (DES5)
This section explains details of Descriptor 5 (DES5).
DES5 Descriptor configuration
Address: DESTP + DESP + 0x10 (ORL[2:0] = x10)
Address: DESTP + DESP + 0x14 (ORL[2:0] = x11)
bit
31
0
Field
DES5[31:0]
C attribute
R/W
D attribute
R
DES5 Descriptor function
bit[31:0] DES5[31:0] (Descriptor 5)
DES5 sets the setting to be loaded to DES2 (transfer source start address) in OuterReload. Set DES5 to
the same value as DES2. The DSTC does not modify the value of this area.
5.19 Descriptor 6 (DES6)
This section explains details of Descriptor 6 (DES6).
DES6 Descriptor configuration
Address: DESTP + DESP + 0x10 (ORL[2:0] = 100)
Address: DESTP + DESP + 0x14 (ORL[2:0] = 110, 101)
Address: DESTP + DESP + 0x18 (ORL[2:0] = 111)
bit
31
0
Field
DES6[31:0]
C attribute
R/W
D attribute
R
DES6 Descriptor function
bit[31:0] DES6[31:0] (Descriptor 6)
DES6 sets the setting to be loaded to DES3 (transfer destination start address) in OuterReload. Set
DES6 to the same value as DES3. The DSTC does not modify the value of this area.
