Description
CLK
21
I
PCI Clock: PCI clock provides timing for all transaction on SB16C1052PCI.
RESET#
19
I
PCI Reset: Reset the SB16C1052PCI. The inputted signal indicates when the
applied main power is within the specified tolerance and stable. This signal is
asynchronous to CLK when asserted or deasserted.
INTA#
18
O/D
Interrupt A: Interrupt A is used to request an interrupt. Interrupts on PCI are
defined as level sensitive, asserted low, using open drain output drivers. The
assertion and deassertion of INTA# is asynchronous to CLK.
PME#
23
O/D
Power Management Event: This signal can be used by SB16C1052PCI to
request a change in the SB16C1052PCI or main system power state. The
assertion and deassertion of PME# is asynchronous to CLK. This signal has
additional electrical requirements over and above standard open drain signals
that allow it to be shared between devices that are powered off and those that
are powered on.
The use of this pin is specified in the PCI Bus Power Management Interface
Specification.
