7.15 Peripheral Component Interconnect (PCI)
The DM6467T DMSoC supports connections to PCI-compliant devices via the integrated PCI master/slave
bus interface. The PCI port interfaces to DSP internal resources via the data switched central resource.
The data switched central resource is described in more detail in
bus interface. The PCI port interfaces to DSP internal resources via the data switched central resource.
The data switched central resource is described in more detail in
, System Interconnect.

7.15.1 PCI Device-Specific Information
The PCI peripheral on the DM6467T DMSoC conforms to the PCI Local Bus Specification Revision 2.3.
The PCI peripheral can act both as a PCI bus master and as a target. It supports PCI bus operation of
speeds up to 66 MHz and uses a 32-bit data/address bus.
The PCI peripheral can act both as a PCI bus master and as a target. It supports PCI bus operation of

On the DM6467T device, the pins of the PCI peripheral are multiplexed with the pins of the EMIFA, GPIO,
HPI, and ATA peripherals. For more detailed information on how to select PCI, see
HPI, and ATA peripherals. For more detailed information on how to select PCI, see

Configurations.
The DM6467T device provides an initialization mechanism through which the default values for some of
the PCI configuration registers can be read from an I2C EEPROM.
