eXtended FAXENGINE™ Device Set
Introduction
The Rockwell eXtended FAXENGINE™ Device Set
consists of a Rockwell eXtended Facsimile Controller
(XFC) device and a Rockwell MONOFAX® Modem
device. This family of eXtended FAXENGINE (XFE)
devices provides upgradability via its hardware and
software compatible controllers.
Starting with the basic eXtended Facsimile Controller
(XFC-B), combinations of voice (-V), page memory (-M),
plain paper support (-P), and full-duplex speakerphone (-
S) support can be added. Voice operation provides 12
minutes (-V12) or 24 minutes (-V24) of digital telephone
answering machine (DTAM) recording. Telephone line
rates up to 9600 bps (R96) or 14400 bps (R144) are
supported. The XFE Device Set models and the
supported major functions are listed in Table 1.
Each eXtended FAXENGINE Device Set, including
supplied firmware, comprises a complete facsimile
machine controller–needing only a power supply, scanner,
printer and paper path components to complete the
machine.
The FAXENGINE Development System including the
FAXENGINE Evaluation System (FEES-X) and the MC24
ROM Emulator (McFERE) provides an effective
development environment.

R144EFXL and R96DFXL support V.29 and V.17 fax
machines, while the RFX modems add integrated
fax/digital answering machine functionality by providing a
voice codec that yields up to 12 (V12) or 24 (V24) minutes
of voice storage per 4 Mbits of memory.
The RFX-S modems support the full range of features
listed above and add DigiTalk™ full-duplex speakerphone
features for “Natural” hand-free applications. An
integrated Analog front-end (IA) is added to support full-
duplex speakerphone operation.
FAXENGINE Firmware
The FAXENGINE firmware includes a complete software
package–core code and application code–for the
development of a customized facsimile machine. The
following features are supported by the firmware:
•

Code is provided in object code form ready for linking to
developer-provided application program object code. The
Core Code is highly structured for maximum application
flexibility with minimum overhead.
Application Code.
The Application Code “builds” an
example fax machine using the XFE device set in the
FEES-X environment. This code is provided in source
code form and serves as basis for the developer’s
application.
Description
FAXENGINE eXtended Facsimile Controller
The XFC provides design flexibility by virtue of its built-in
peripheral functions (e.g., scanner, printer, and operator
interfaces) and programmable hardware registers.
The XFC performs the primary facsimile machine control
and monitoring functions, interfacing with all major fax
machine components. The MC24™ embedded processor
provides an 8-bit data bus, a 24-bit internal address bus
and a direct external memory accessing capability of 16
Mbytes (2 Mbytes for the XFC-B).
Scanner, printer, and keyboard interfaces, as well as
motor control and the modem interface, are included.
MD139
FAXENGINE Development System
The Rockwell FAXENGINE Evaluation System (FEES-X)
and MC24 FERE ROM Emulator provides demonstration,
prototype development, and evaluation capabilities to
facsimile machine developers using the eXtended
FAXENGINE Device Set. The FEES-X offers flexibility for
visibility and access. It supplies the Modem Evaluation
Board with Data Access Arrangement (DAA), sockets for
programmable parts, and connectors for an emulator and
all fax machine peripherals. The ROM Emulator (MC24
3
XFE
FERE) is a PC-based code development aid with
breakpoint and trace capability for debugging firmware.
eXtended FAXENGINE Device Set
internal XFC functions over a internal 24-bit address bus,
8-bit data bus, and dedicated control lines. The bus is
routed outside the XFC for external memory access. The
external address bus is 24-bit except for the XFC-B which
provides a 20-bit external address bus.
External Bus Control
Address, data, control, status, interrupt, and decoded chip
select signals support connection to external ROM,
external RAM, and optional DRAM and peripheral devices.
Dedicated internal DMA logic is included for scanner,
printer and T.4 access of internal and/or external RAM.
Five (three for XFC-B) internal DMA channels support
scanner, printer and T.4 access of the external shading
and line buffer RAM. A sixth DMA channel is available to
support T.4/T.6 access to external page memory
(“External DMA” column, Table 1) or to plain paper printer
engines.
Hardware Description
The XFE system-level functional interface is shown in
Figure 1. (Note: The suffix n indicates an active low sig-
nal.)
eXtended Facsimile Controller (XFC)
The XFC contains an internal 8-bit microprocessor with a
16-Mbyte (XFC-B: 2-Mbyte) external address space and
dedicated circuitry optimized for facsimile image
processing, data compression/decompression and for
facsimile machine control and monitoring.
Microprocessor
The microprocessor is an enhanced MC24 central
processing unit (CPU). This CPU provides fast instruction
(10 MHz clock speed) execution and memory efficient
input/output bit manipulation. The CPU connects to other
