17.5.5
Programming Interface (PI)—Offset 9h
This register definition depends on the CC.SCC field. When the CC.SCC is 01h(IDE
mode), register definition corresponds to 1st table. When CC.SCC is 06h(AHCI mode),
register definition follows the 2nd table.
Access Method
Default: 8Ah

Bus Master Support (BMS):
Indicates the SATA Controller supports bus master
operation.

RO
Secondary Mode Native Capable (SNC):
Indicates that the secondary controller
supports both legacy and native modes.
2
0h
RW
Secondary Mode Native Enable (SNE):
Determines the mode that the secondary
channel is operating in. 0 corresponds to 'compatibility', 1 means PCI native. If this bit is
set by SW, then the PNE bit must also be set by SW. While in theory these bits can be
programmed separately, such a configuration is not supported by today's software and
is not supported by this hardware. If this bit is left unchanged before switching, the
result is indeterminate.

Primary Mode Native Capable (PNC):
Indicates that the primary controller supports
both legacy and native modes.
