5
Hot-Plug Surprise
RO
When set, it indicates that a device present in this slot might be removed from
the system without any prior notification. The default value may be changed
by SMBus or auto-loading from EEPROM.
Reset to 0b.
6
Hot-Plug Capable
HwInt
When set, it indicates that this slot is capable of supporting Hot-Plug
operation. The default value may be changed by the status of strapped pin or
auto-loading from EEPROM.
14:7
Slot Power Limit
Value
RW
It applies to Downstream Port only. In combination with the Slot Power Limit
Scale value, specifies the upper limit on power supplied by slot. Writes to this
register also cause the Port to send the Set_Slot_Power_Limit message. The
default value may be changed by SMBus or auto-loading from EEPROM.
Reset to 00h.
16:15
Slot Power Limit
Scale
RW
It applies to Downstream Port only. Specifies the scale used for the Slot
Power Limit Value. Writes to this register also cause the Port to send the
Set_Slot_Power_Limit message. The default value may be changed by
SMBus or auto-loading from EEPROM.
Reset to 00b.
18:17
Reserved
RO
Reset to 00b.
31:19
