Reserved
Reserved for Data Link Layer State Changed Enable
(DLLSCE)
If the Data Link Layer Link Active capability is implemented,
when set to 1b, this field enables software notification when
Data Link Layer Link Active field is changed.
If the Data Link Layer Link Active capability is not
implemented, this bit is permitted to be read-only with a
value of 0b.
Reserved for Electromechanical Interlock Control (EIC)
If an Electromechanical Interlock is implemented, a write of
1b to this field causes the state of the interlock to toggle. A
write of 0b to this field has no effect. A read to this register
always returns a 0.
Reserved for Power Controller Control (PCC)
If a Power Controller is implemented, this field when written
sets the power state of the slot per the defined encodings.
Reads of this field must reflect the value from the latest write,
even if the corresponding hot-plug command is not complete,
unless software issues a write without waiting for the
previous command to complete in which case the read value
is undefined.
Depending on the form factor, the power is turned on/off
either to the slot or within the adapter. Note that in some
cases the power controller may autonomously remove slot
power or not respond to a power-up request based on a
detected fault condition, independent of the Power Controller
Control setting.
The defined encodings are:
0b Power On
1b Power Off
If the Power Controller Implemented field in the Slot
Capabilities register is set to 0b, then writes to this field have
no effect and the read value of this field is undefined.
