AHCI Registers (D31:F2) (Intel
ICH8DO, and ICH8M-E Only)
These registers are AHCI-specific and available when the ICH8 is properly configured.
The Serial ATA Status, Control, and Error registers are special exceptions and may be
accessed on all ICH8 components if properly configured. See
details.
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.
