MPC8309 PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 2
Freescale Semiconductor 5
Overview
— External and internal interrupts directed to host processor
— Unique vector number for each interrupt source
• PCI interface
— Designed to comply with PCI Local Bus Specification, Revision 2.3
— 32-bit PCI interface operating at up to 66 MHz
— PCI 3.3-V compatible
— Not 5-V compatible
— Support for host and agent modes
— Support for PCI-to-memory and memory-to-PCI streaming
— Memory pre-fetching of PCI read accesses and support for delayed read transactions
— Support for posting of processor-to-PCI and PCI-to-memory writes
— On-chip arbitration, supporting three masters on PCI
— Arbiter support for two-level priority request/grant signal pairs
— Support for accesses to all PCI address spaces
— Support for parity
— Selectable hardware-enforced coherency
— Address translation units for address mapping between host and peripheral
— Mapping from an external 32-/64-bit address space to the internal 32-bit local space
— Support for dual address cycle (DAC) (as a target only)
— Internal configuration registers accessible from PCI
— Selectable snooping for inbound transactions
— Four outbound Translation Address Windows
– Support for mapping 32-bit internal local memory space to an external 32-bit PCI address
space and translating that address within the PCI space
— Four inbound Translation Address Windows corresponding to defined PCI BARs
– The first BAR is 32-bits and dedicated to on-chip register access
– The second BAR is 32-bits for general use
– The remaining two BARs may be 32- or 64-bits and are also for general use
