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 ISAnet evaluation adapter card is designed and
configured for shared memory and PIO operation
mode. The adapter card in the PCnet-ISA II-KT/2 eval-
uation kit is designed and configured 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’s family of Élan
microcontrollers and their evaluation boards. This is
because the Élan family of microcontrollers, in particular,
ÉlanSC300 and ÉlanSC400 series of microcontrollers do
The user should note there is a significant 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,
