DESCRIPTION
The PCI/DMA block provides PCI bus protocol control. The block has the slave function for responding register access from a bus master, the master function for issuing transfer requests from the MB86613 as the bus master, the power management function (compliant with PCI bus power management standard version 1.0), and the interfaces to BIOS ROM and PCI configuration ROM. The OHCI block analyzes context programs pre-stored in host memory to store the packet to be sent out from host memory to the FIFO buffer or to store the received packet from the FIFO buffer to host memory. The 1394 block incorporates the LINK layer module, PHYsical layer module, 1394 transceiver, comparator, and PLL, providing 1394 bus protocol control. The block converts the packet stored in the FIFO buffer to serial data and send it onto the 1394 bus or converts the packet received from the 1394 bus to parallel data and stores it in the FIFO buffer. For packet transmission and reception, the chip supports a transfer rate of up to S400.
