Executive Processor
System Interface Signals
The XP’s system interface manages the supervisory controls for the network interfaces, as
well as the set of pins that provide interfaces to other components in the system that are
not memories or network interfaces. It is also the primary interface used for initializing the
C-5 NP after reset. The XP signals include PCI signals, Serial interface signals, and PROM
interface signals.
PCI Signals
The PCI can be configured to support a 32bit PCI capable of operating at either 33MHz or
66MHz. The PCI is fully compliant with PCVI Specification revision 2.1. Table 12 describes
the PCI signals.

PCI
I/O
Multiplexed Address/Data Bus. These signals are
multiplexed address and data bits. The C-5 NP
receives addresses as target and drives addresses as
master. It drives the data and receives read data as
master.
PCBEX0 - PCBEX3
N21, N20, M20, O20

PCI
I/O
Command byte enables. These signals are
multiplexed command and byte enabled signals.
The C-5 NP receives byte enables as target and drives
byte enables as master.
PPAR
P14
1
PCI
I/O
Parity. This signal carries even parity for AD and CBE#
pins. It has the same receive and drive characteristics
as the address and data bus, except that it is one PCI
cycle later.
