This page specifies the parameters for the control of data compression in a Device.
A Data Compression Enable (DCE) bit of one indicates that the data compression is to be enabled. When this bit
is set, data sent to the Device by the Host shall be processed using the selected compression algorithm before
being written to the medium. A DCE bit of zero indicates that data compression is disabled.
A Data Compression Capable (DCC) bit of one indicates that the Device supports data compression and shall
process data sent to it for transferal to the medium using the selected compression algorithm when the DCE bit is
one. A DCC bit of zero indicates that the Device does not support data compression. This shall be a non-
changeable field.
A Data Decompression Enable (DDE) bit of one indicates that data decompression is to be enabled. A DDE of
zero indicates that data decompression is disabled.
