2.1 Host PCI interface
Provides 32-bit PCI bus master data transfer Supports network operation with PCI system clock from 22 MHz to 33MHz Provides performance meter, PCI bus master latency timer, for tuning the threshold to
enhance the performance
Provides burst-transmit packet interrupt and transmit/receive early interrupt to reduce host
CPU utilization.
Supports memory-read, memory-read-line, memory-read-multiple, memory-write,
memory-write-and-invalidate command while being bus master
Supports big or little endian byt e ordering Arbitration between DMA channel to minimize underflow or overflow
