For more about descriptor types and the data used for each type, see
14.3.3
The descriptor contains seven ‘pointer dwords,’ which define where in memory the SEC should access its
input and output data parcels. The pointer dwords are numbered 0–6 as shown in
determines how it will use each of the pointer dwords based on the ‘Descriptor Type’ and ‘Direction’ fields
in the header. The channel accesses the first data parcel by starting at a location given by a POINTER
value, and accessing a number of bytes given by a LENGTH or EXTENT value. Subsequent data parcels
may be accessed by starting where a previous data parcel ended, or by starting at a different POINTER.
The LENGTH or EXTENT used with any POINTER may be from the same pointer dword or from a
different pointer dword in the same descriptor. Although the EXTENT field exists in each pointer dword
of the SEC descriptor, only the EXTENTs in pointer dwords 3, 4, and 5 are currently in use.

LENGTH
Length. A number of bytes in the range 0–65535. The use of this field depends on the ‘Descriptor
Type’ and ‘Direction’ in the header dword. A value of zero causes the channel to skip this dword.
Jump. Determines whether to ‘jump’ to a link table whenever the POINTER field in this same lword is
used.
0 The POINTER field points to data.
1 The POINTER field points to a link table, and scatter/gather is enabled.
Extent. A number of bytes in the range 0–127. The use of this field depends on the ‘Descriptor Type’
and ‘Direction’ in the header dword.
