Serial ATA Data (SDATA)—Offset 4h
All of these I/O registers are in the core well. They are exposed only when CC.SCC is
01h (i.e. IDE programming interface). These are Index/Data Pair registers that are
used to access the SerialATA superset registers (SerialATA Status, SerialATA Control
and SerialATA Error). The I/O space for these registers is allocated through SIDPBA.
Locations with offset from 08h to 0Fh are reserved for future expansion. Software write
operations to the reserved locations shall have no effect while software read operations
to the reserved locations shall return 0. Refer to Serial ATA Index/Data Pair Superset
Registers for more details.

Data (DATA):
This Data register is a window through which data is read or written to
from the register pointed to by the Serial ATA Index (SINDX) register above. Note that a
physical register is not actually implemented as the data is actually stored in the
memory mapped registers. Since this is not a physical register, the default value is the
same as the default value of the register pointed to by SINDX.RIDX field.
