22.1
The PCI Controller (PCIC) controls the PCI bus and transfers data between memory connected to
the external bus and a PCI device connected to the PCI bus. The ability for PCI devices to be
connected directly not only facilitates the design of systems using PCI buses but also enables
systems to be more compact and capable of high-speed data transfer.
22.1.1
The PCIC has the following features:
• Supports a subset of PCI version 2.1.
• Compatible with PCI bus operating speeds of 33 MHz/66 MHz.
• Compatible with 32-bit PCI bus.
• Up to four PCI master devices running at 33 MHz or one PCI master device at 66 MHz can be
• Arbitration control is available as a PCI host function.
• Can operate as master or target.
• When operating as master, PIO and DMA transfer are available.
• Four DMA transfer channels.
• Six 32-bit x 16 longword internal FIFO (one for target reading, one for target writing, and four
• Asynchronous operation of BSC bus clock and PCI bus clock available, and CKIO can be used
• SRAM, DRAM, SDRAM, and MPX* can be used as external memory for PCI bus data
• 32-bit or 16-bit memory data bus for data transfers with PCI bus (32-bit bus when connected to
