Table 12-3. AHCI Register Address Map
Table 12-4. Generic Host Controller Register Address Map
Note: These registers are AHCI-specific and available only on ICH6R and ICH6-M when properly
AHCI Registers (D31:F2)
configured. The Serial ATA Status, Control, and Error registers are special exceptions and may be
accessed on all ICH6 components if properly configured; see
The memory mapped registers within the SATA controller exist in non-cacheable memory space.
Additionally, locked accesses are not supported. If software attempts to perform locked
transactions to the registers, indeterminate results may occur. Register accesses shall have a
maximum size of 64-bits; 64-bit access must not cross an 8-byte alignment boundary.
The registers are broken into two sections – generic host control and port control. The port control
registers are the same for all ports, and there are as many registers banks as there are ports.
