Introduction
Figure 1.1
L64381 Block Diagram
The chip provides several programmable configurations to allow cus-
tomer product differentiation, such as source address insertion, FCS
insertion, immediate retransmission on collision, bus transfer size, and
transmit buffer threshold size.
The L64381 can be configured using the 6-bit Address bus and the 16-bit
PData bus. All the internal registers can be read, and most also can be
written. Special test modes are provided that make functional and in
system testing simpler.
