Description
0
Ports Implemented Port 0 (PI0) — R/WO.
0 = The port is not implemented.
1 = The port is implemented.
VS—AHCI Version (D31:F2)
Address Offset: ABAR + 10h–13h
Default Value: 00010100h
Attribute:
Size:
RO
32 bits
This register indicates the major and minor version of the AHCI specification. It is BCD
encoded. The upper two bytes represent the major version number, and the lower two
bytes represent the minor version number. Example: Version 3.12 would be
represented as 00030102h. The current version of the specification is 1.10
(00010100h).
Bit
Description
31:16 Major Version Number (MJR) — RO. Indicates the major version is 1
15:0 Minor Version Number (MNR) — RO. Indicates the minor version is 10.
