PEXSLOTCTRL[7:2, 0] - PCI Express* Slot Control Register
The Slot Control register identifies the PCI Express* specific slot control specific
parameters for operations such as PCI Hot Plug* and Power Management. Software
issues a command to a PCI Hot Plug* capable Port by issuing a write transaction that
targets Slot Control Register fields viz, PWRCTRL, PWRLED, ATNLED described below. A
single write to the Slot Control register is considered to be a single command, even if
the write affects more than one field in the Slot Control register. In response to this
transaction, the port must carry out the requested actions and then set the associated
status field (PEXSLOTSTS.CMDCMP) for the command completed event. The PCI Hot
Plug* capabilities of this register are not supported for the Intel
default values to be maintained. The PEXSLOTSTS.CMDCMP bit will be set only when
there is a unique change to the state of the PWRCTRL, PWRLED, ATNLED in this
register.
The ESI port, device 0, does not support PCI Hot Plug* capabilities.
