Interrupt Disable — R/W.
0 = Enables the SATA host controller to assert INTA# (native mode), IRQ14/15 (legacy mode), and
1 = The interrupt will be deasserted and it may not generate MSIs.
Fast Back to Back Enable (FBE) — RO. Reserved as 0.
SERR# Enable (SERR_EN) — RO. Reserved as 0.
Wait Cycle Control (WCC) — RO. Reserved as 0.
Parity Error Response (PER) — R/W.
0 = Disabled. SATA controller will not generate PERR# when a data parity error is detected.
1 = Enabled. SATA controller will generate PERR# when a data parity error is detected.
VGA Palette Snoop (VPS) — RO. Reserved as 0.
Postable Memory Write Enable (PMWE) — RO. Reserved as 0.
Special Cycle Enable (SCE) — RO. Reserved as 0.
Bus Master Enable (BME) — R/W. This bit controls the Intel
for IDE Bus Master transfers. This bit does not impact the generation of completions for split
transaction commands.
Memory Space Enable (MSE) — RO. The SATA controller does not contain memory space.
I/O Space Enable (IOSE) — R/W. This bit controls access to the I/O space registers.
0 = Disables access to the Legacy or Native IDE ports (both Primary and Secondary) as well as the
1 = Enable. Note that the Base Address register for the Bus Master registers should be
MSI (if MSI is enabled).
