This ﬁeld is always empty.

Indicates the value of the parameter itself. The length varies in accordance with the data size indicated by the

"dlen" ﬁeld, as shown below. This ﬁeld is not included for a parameter request.

Each block of data is packed from the lowest order byte ﬁrst. In the case of multiple-byte data, the least

signiﬁcant bit is the LSB of the ﬁrst "data" block, and the most signiﬁcant bit is the MSB of the ﬁnal "data"

block.

The following shows an example of how data would be divided for transfer in the case of 32-bit data.
