EEEEEEEE is a mask as defined by the Request
Primitive and DDDD is defined by the data type being
accessed. The order of return of the blocks is from the
lowest numbered block to the highest. For example, if
blocks 2, 4, and A were requested, the first data block
in the response specifies data which is associated with
block 2, the next data block specifies data which is
associated with block 4, etc. This field can be set to
zero if you want to perform a write function without
reading a block.
