Parameter Data
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.
