GEOGRAPHICAL ADDRESSING
The Katana
752i has three read-only registers that allow the software to read Geographical
Addresses from the CompactPCI backplane connectors. The following table describes
these registers.

PCI BUS CONTROL SIGNALS
This section lists signals for the PCI interface which are available on PMC connectors J11,
J12, J21, and J22 (see also pinout tables beginning on page 9-3). Please refer to the PCI
specification for details on using these signals. All signals are bi-directional unless otherwise
stated.
