MRL Sensor Changed Enable (MSE) — R/W. MSE not supported.
Power Fault Detected Enable (PFE) — R/W. PFE not supported.
Attention Button Pressed Enable (ABE) — R/W. When set, enables the generation
of a Hot-Plug interrupt when the attention button is pressed.
0 = Disable. Hot plug interrupts based on the attention button being pressed is
1 = Enables the generation of a Hot-Plug interrupt when the attention button is
Reserved
Link Active State Changed (LASC) — R/WC. This bit is set when the value reported
in Data Link Layer Link Active field of the Link Status register (D28:F0/F1/F2/F3/F4/
F5:52h:bit 13) is changed. In response to a Data Link Layer State Changed event,
software must read Data Link Layer Link Active field of the Link Status register to
determine if the link is active before initiating configuration cycles to the hot plugged
device.
0 = No change.
1 = Change
Reserved
Presence Detect State (PDS) — RO. If XCAP.SI (D28:F0/F1/F2/F3/F4/F5:42h:bit 8)
is set (indicating that this root port spawns a slot), then this bit:
0 = Slot is empty.
1 = Slot has a device connected.
Otherwise, if XCAP.SI is cleared, this bit is always set to 1.
MRL Sensor State (MS) — Reserved as the MRL sensor is not implemented.
Command Completed (CC) — R/WC.
0 = Issued command not completed.
1 = The Hot-Plug controller completed an issued command. This is set when the last
Presence Detect Changed (PDC) — R/WC.
0 = No change in the PDS bit.
1 = The PDS bit changed states.
MRL Sensor Changed (MSC) — Reserved as the MRL sensor is not implemented.
Power Fault Detected (PFD) — Reserved as a power controller is not implemented.
Attention Button Pressed (ABP) — R/WC.
0 = The attention button has Not been pressed.
1 = The attention button is pressed.

pressed.
message of a command is sent and indicates that software can write a new
command to the slot controller.
