Reserved for Attention Indicator Control (AIC)
If an Attention Indicator is implemented, writes to this field set
If an Attention Indicator is implemented, writes to this field set
the Attention Indicator to the written state. 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. If the
indicator is electrically controlled by chassis, the indicator is
controlled directly by the downstream port through
implementation specific mechanisms.
