Freescale Semiconductor MPC8260 1.7.2.5 PCI with 155-Mbps ATM

Overview
MPC8260 PowerQUICC II Family Reference Manual, Rev. 2
1-22 Freescale Semiconductor
Figure 1-12. PCI Configuration
In this system the local bus is configured as PCI (33-MHz 32-bit data bus version 2.1). The PowerQUICC
II can be configured as a host or as an agent on the PCI bus. The 60x bus and PCI bus are asynchronous;
there is no frequency dependency between the two. The PCI bus is a 3.3-V bus.
1.7.2.5 PCI with 155-Mbps ATM
Figure 1-13 shows the PCI with 155-Mbps ATM configuration (MPC8265 and MPC8266 only).
Figure 1-13. PCI with 155-Mbps ATM Configuration
This system supports PCI and implements a 155-Mbps, full-duplex ATM with more than 128 active
connections. The PowerQUICC II cannot support both functions simultaneously. The local bus is needed
