5RW 0h
Hot-plug Interrupt Enable
When set to 1b, this bit enables generation of Hot-Plug MSI interrupt (and
not wake event) on enabled Hot-Plug events, provided ACPI mode for
hotplug is disabled.
0: disables interrupt generation on Hot-plug events
1: enables interrupt generation on Hot-plug events
4RW 0h
Command Completed Interrupt Enable
This field enables the generation of Hot-plug interrupts (and not wake event)
when a command is completed by the Hot-plug controller connected to the
PCI Express port
0: disables hot-plug interrupts on a command completion by a hot-plug
Controller
1: Enables hot-plug interrupts on a command completion by a hot-plug
Controller
3RW 0h
Presence Detect Changed Enable
This bit enables the generation of hot-plug interrupts or wake messages via
a presence detect changed event.
0: Disables generation of hot-plug interrupts or wake messages when a
presence detect changed event happens.
1: Enables generation of hot-plug interrupts or wake messages when a
presence detect changed event happens.
2RW 0h
MRL Sensor Changed Enable
This bit enables the generation of hot-plug interrupts or wake messages via
a MRL Sensor changed event.
0: Disables generation of hot-plug interrupts or wake messages when an
MRL Sensor changed event happens.
1: Enables generation of hot-plug interrupts or wake messages when an MRL
Sensor changed event happens.
1RW 0h
Power Fault Detected Enable
This bit enables the generation of hot-plug interrupts or wake messages via
a power fault event.
0: Disables generation of hot-plug interrupts or wake messages when a
power fault event happens.
1: Enables generation of hot-plug interrupts or wake messages when a
power fault event happens.
0RW 0h
Attention Button Pressed Enable
This bit enables the generation of hot-plug interrupts or wake messages via
an attention button pressed event.
0: Disables generation of hot-plug interrupts or wake messages when the
attention button is pressed.
1: Enables generation of hot-plug interrupts or wake messages when the
attention button is pressed.
