PRINCIPLES OF OPERATION
interfaces
The PCI SAR (TNETA1561) has the interfaces shown in Figure 13. The PCI-bus interface communicates with
any other host on the PCI bus. The local-bus interface allows PCI SAR to have access to PHY-layer device
registers and to an external EPROM. The control-memory interface allows the host and other internal functions
of the PCI SAR to access the control memory. The PHY-layer interface allows the PCI SAR to transmit packets
to a PHY-layer device or receive cells from it.
