ATNLED: Attention Indicator Control
This bit indicates the current state of the Attention Indicator of the PCI
Express
port
00: Reserved.
01: On
10: Blink (The Intel 5000P Chipset MCH drives 1.5 Hz square wave)
11: Off
Default is set to 11b (OFF)
When this field is written, the Intel 5000P Chipset MCH sends appropriate
ATTENTION_INDICATOR messages through the PCI Express port. For legacy
card based PCI Express devices, the event is signaled via the virtual pins of
the Intel 5000P Chipset MCH, in addition. For PCI Express modules with
advanced form factor that incorporate LEDs and onboard decoding logic, the
PCI Express messages are interpreted directly (No virtual pins).
HPINTEN: Hot-Plug Interrupt Enable
This field enables the generation of hot-plug interrupts and events in the PCI
Express port.
0: disables hot-plug events and interrupts
1: enables hot-plug events and interrupts
CCIEN: Command Completed Interrupt Enable
This field enables the generation of hot-plug interrupts 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.
PRSINTEN: 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.
MRLINTEN:
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.
PWRINTEN:
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.
