PCS—Port Control and Status Register (SATA–D31:F2)
Address Offset:
Default Value:
This register is only used in systems that do not support AHCI. In AHCI enabled systems, bits[3:0]
must always be set (ICH6R only) / bits[2,0] must always be set (ICH6-M only), and the status of
the port is controlled through AHCI memory space.

Port 3 Present (P3P) — RO. The status of this bit may change at any time. This bit is cleared when
the port is disabled via P3E. This bit is not cleared upon surprise removal of a device.
0 = No device detected.
1 = The presence of a device on Port 3 has been detected.

Port 2 Present (P2P) — RO. The status of this bit may change at any time. This bit is cleared when
the port is disabled via P2E. This bit is not cleared upon surprise removal of a device.
0 = No device detected.
1 = The presence of a device on Port 2 has been detected.
Port 1 Present (P1P) — RO. The status of this bit may change at any time. This bit is cleared when
the port is disabled via P1E. This bit is not cleared upon surprise removal of a device.
0 = No device detected.
1 = The presence of a device on Port 1 has been detected.

Port 0 Present (P0P) — RO. The status of this bit may change at any time. This bit is cleared when
the port is disabled via P0E. This bit is not cleared upon surprise removal of a device.
0 = No device detected.
1 = The presence of a device on Port 0 has been detected.
Port 3 Enabled (P3E) — R/W.
0 = Disabled. The port is in the ‘off’ state and cannot detect any devices.
