GENERAL DESCRIPTION
The ISAnet evaluation kit meets the needs of custom-
ers working with embedded networking control applica-
tions using the Am79C961A PCnet-ISA II single-chip
Ethernet controller. The evaluation kit contains hard-
ware, software, and documentation to facilitate the de-
sign of embedded networking control applications
based on the PCnet-ISA II controller.
The user should note there is a
signi鏗乧ant difference
between ISAnet evaluation adapter card used here and
the PCnet-ISA II evaluation adapter card used in the
PCnet-ISA II-KT/2 Evaluation Kit
. While both adapter
cards are ISA-based adapter cards and both are based
on the Am79C961A PCnet-ISA II Ethernet controller,
the ISAnet evaluation adapter card is designed and
con鏗乬ured for shared memory and PIO operation
mode. The adapter card in the PCnet-ISA II-KT/2 eval-
uation kit is designed and con鏗乬ured for bus-mastering
operation mode.
The design of the ISAnet adapter card provides an
Ethernet feature that can be added to other platforms with
ISA slots to allow for system development in a shared
memory mode environment. In particular, the ISAnet
adapter card is ideal for use with AMD鈥檚 family of
脡
lan
microcontrollers and their evaluation boards. This is
because the
脡
lan family of microcontrollers, in particular,
脡
lanSC300 and
脡
lanSC400 series of microcontrollers do
