***Info:
The CS8281 NEATsx CHlPSet, which  is composed of four VLSI devices, is
a  high-performance, 100%-compatible  enhanced  implementation of  the
control logic used in the IBM  PC AT. The flexible architecture of the
NEATsx  CHIPSet   allows  it  to  be   used  as  the   basis  for  any
386sx-compatible system.

The CS8281  NEATsx CHIPSet provides a complete  386sx PC/AT compatible
system, requiring only 24 logic components plus memory devices.

The CS8281  NEATsx CHIPSet consists of the  82C811 CPU/bus controller,
the  82C812  page/interleave and  EMS  memory  controller, the  82C215
data/address buffer, and  the 82C206 integrated peripherals controller
(IPC).

The NEATsx  CHIPSet supports a local  CPU bus, a  16-bit system memory
bus, and the AT buses as shown in the NEATsx system block diagram [see
datasheet].  The  82C811 provides synchronization  and control signals
for all buses.   The 82C811 also provides an  independent AT bus clock
and allows  for dynamic  selection between the  processor clock  and a
user~selectable AT bus clock.   Because command delays and wait states
are  configured  by  software,  peripheral boards  are  provided  with
maximum flexibility.

The  82C812  page/interleave and  EMS  memory  controller provides  an
interleaved memory subsystem design with page mode operation.  It sup-
ports up to 8MB of DRAM  with combinations of 256Kb and 1Mb DRAMs. The
processor can operate  at 16 MHz with 0.7  wait state memory accesses,
using 100  nsec DRAMs.   This is possible  through a  page interleaved
memory  scheme. A  RAM shadowing  feature allows  faster  execution of
EPROM stored BIOS code by downloading and executing code from RAM.  in
a DOS environment memory above 1MB can be used as EMS memory.

The 82C215 data/address buffer provides buffering and latching between
the  local CPU address  bus and  the peripheral  address bus.  It also
provides buffering between the local  CPU data bus and the memory data
bus.  Parity bit  generation and error detection logic  resides in the
82C215.  

The 82C206  integrated peripherals controller  is an integral  part of
the NEATsx CHIPSet.  It is described in the 82C206 data book.

System Overview
The CS8281 NEATsx CHIPSet is designed for use in 12-16 MHz 80386 based
systems  and provides complete  support for  the IBM  PC AT  bus. Four
buses are supported by the CS8281 NEATsx CHIPSet: the CPU local bus (A
and D); the system memory bus (MA and MD); the I/O channel bus (SA and
SD); and  the X  bus (XA and  XD). The  system memory bus  provides an
interface between the  CPU and the DRAMs and  EPROMS controlled by the
82C812.   The  I/O  channel  bus  refers to  the  bus  supporting  the
AT-compatible bus adapters  which can be either 8-  or 16-bit devices.
The X  bus is  the peripheral bus  to which  the 82C206 IPC  and other
peripherals are attached in an IBM PC AT.
