14 PIP RWL 0x0 Power Indicator Present. When set, this bit indicates that
a Power Indicator is implemented on the card/module. This
bit should not be set on downstream ports.
25:18 CSPLV RO 0x0 Captured Slot Power Limit Value. (Upstream Port A only,
hardwired to zero in downstream ports) Captured Slot
Power Limit Value (upstream Ports only, hardwired to zero
in downstream ports) – In combination with the Slot Power
Limit Scale value, specifies the upper limit on power sup-
plied by slot.Power limit (in Watts) calculated by multiplying
the value in this field by the value in the Slot Power Limit
Scale field.
This value is set by the Set_Slot_Power_Limit Message
27:26 CSPLS RO 0x0 Captured Slot Power Limit Scale. (Upstream Port A only,
hardwired to zero in downstream ports) This field specifies
the scale used for the Slot Power Limit Value and is set via
a Set_Slot_Power_Limit message.
