S5 UniLink Adapter Installation and Operation

The Write and Gather Block primitive specifies which blocks (as defined

with Define Block primitive 50) will be read. It also allows a user to replace

any contiguous data element locations. The blocks are specified through a

32-bit mask (EEEEEEEE).

The Write occurs first, followed by the Gather. Refer to Gather Block for the

bit masking information and other related items concerning the operation of

this primitive.
