Command Specifications
The "PC" bits are ignored by the drive. The drive assumes that current cumulative
parameters are selected.
The "Parameter List Length" field specifies the length in bytes of the parameter list
that is located in the Data-Out Buffer. If a parameter list length results in the truncation
of any log parameter, the IDD terminates this command with CHECK CONDITION
status (ILLEGAL REQUEST [=5] / Invalid field in CDB [=24-00]).
A "Parameter List Length" of zero indicates that no pages shall be transferred.
This condition shall not be considered an error.
The IDD does not support that the application client should send
pages in ascending order by page code value if the Data-Out Buffer
contains multiple pages.
