Overview
This application note describes a fully PCI-compliant Master/Slave
interface. It utilizes the
PCI burst transfer mode for transfers at high speed, up to 67 MBytes per
second. Although it
is designed to interface the Seeq 80C300 Ethernet Data Link Controller
to the PCI bus, it can
be easily modified to interface with other peripherals. Data is transferred
between System
Memory and the Ethernet controller in bursts of eight using Master Mode
DMA. Internal
80C300 programming registers are mapped into host memory space and
are accessed using
slave mode.
