Description
I Parallel Mode Hot-Plug Power Controller Fault indication for over-
Sync(B) current/under-volt status. When asserted, the device (when enabled)
Rst(B) may assert a slot reset and disconnects the slot from the bus.
I
Sync(B)
Rst(B)
Parallel Mode Hot-Plug Status of the slot 1 MRL sensor switch,
when asserted it indicates the MRL latch is closed. When a platform
does not support MRL sensors, this must be wired to a logic low
level.
I
Sync(B)
Parallel Mode Hot-Plug PRSNT2 signal is used to indicate whether
a card is installed in the slot and its power requirements. These
signals are directly connected to the present bits on the PCI card.
O Parallel Mode Hot-Plug Power Enable signal connected to on-
Sync(B) board slot specific power controller to regulate current and voltage of
Rst(B) the slot.
I Parallel Mode Hot-Plug PRSNT1 signal is used to indicate whether
Sync(B) a card is installed in the slot and its power requirements. These
Rst(B) signals are directly connected to the present bits on the PCI card.
O
Sync(B)
Rst(B)
Parallel Mode Hot-Plug Attention indicator LED signal that is
yellow or amber in color.
O
Sync(B)
Rst(B)
Parallel Mode Hot-Plug Power Indicator LED signal that is green
in color.
I
Sync(B)
Rst(B)
Parallel Mode Hot-Plug Attention Button input from the slot. When
low, this indicates that the operator has requested attention. When
an attention button is not implemented, this input must be wired to a
logic high level.
O
Parallel Mode Reset Output Signal. This output signal is always
“on”, therefore, it does not tri-state during boundary scan.
