1 Overview

The RMB-167 is an evaluation board for the Siemens SAB C167 microcontroller. The RMB-167
board accepts the following processors, the SAB C167-LM, the SAB C167SR-LM, and the SAB
C167CR-LM. The evaluation board is designed as a low-cost demonstration board using the
microcontroller in the 16-bit non-multiplexed addressing mode. The microcontroller is configured
to run at 40Mhz with no wait states. The SAB C167SR-LM, and the SAB C167CR-LM use a
5Mhz oscillator with a phase-lock-loop to generate the ccorrect operating speed. A 16-bit
nonmultiplexed data bus and an 18-bit nonmultiplexed address bus are implemented. Several
memory options are supported. The default configuration is the 64K RAM and no EPROM mode.
In this mode, the monitor program or user program is downloaded to RAM using the SAB C167
bootstrap feature. All system address, data, and control lines as well as microcontroller ports 2
through 8 are terminated at three 50-post headers. The SAB C167 serial port is available to the
user at RS-232 level through a DB-9 socket and a 3-post connector. The serial port is used to
communicate to a PC host. A set of option headers, decoded by GAL devices make the RMB­167 a flexible hardware platform.

1.2 READS166 Evaluation Software Overview

READS166, version 3.00, is Rigel Corporation’s Integrated Development Environment for the
Siemens/SGS Thomson 16-bit processors. READS166 includes an editor, a host-to-board
communications system, an assembler, and a C compiler. READS166 is completely rewritten in
native 32-bit code to run on Windows95 and WindowsNT. READS166 includes a sophisticated
project management system to simplify code reusability and version control. The C compiler is
rewritten to support a full debugger. The debugger allows you to step through your code with
breakpoints and variable watches as the compiled code runs on the target board, similar to the
operation of an in-circuit emulator.

RMON166 - The READS166 monitor program

RMON 166 is downloaded after bootstrapping (or it may be placed into ROM) and supports basic
memory and port functions. RMON166 allows downloading and running applications programs.
The complete source code for user modifications or upgrades is included on disk.

Ra66 - The READS166 Assembler

Ra66 is an assembler for the C166 family of controllers. It is a multi-pass absolute assembler
which generates HEX code directly from assembly source code. The assembler in the demo
version of READS166 limits the size of code to about 2K.

Rc66 - The READS166 C Compiler

Rc66 is a C Compiler for the C166 family of processors. It compiles code for the tiny memory
model which fully resides in the first segment of memory. Rc66 is a designed as a low-cost C
compiler which provides a quick development cycle for simpler applications which do not need
more than 64K of code, or the use of standard C libraries. Rc66 implements a subset of ANSI C.
Rc66 works in conjunction with Ra66: first an assembly language program is generated from the
C source, then a HEX file is generated.

Currently, structures, unions, enumerated types, and the typedef directive are not implemented.
The C-compiler in the demo version of READS166 limits the size of code to about 8K.

2 SOFTWARE

The RMB-167 board comes with software from Rigel Corporation and third party vendors, whom
we work very closely with. Rigel’s own software for the 166 family may be found on the CD-ROM
in the Rigel Products file, under 166 Software.

2.1 System Requirements

READS166 is designed to work with an IBM PC or compatible, 486 or better, running Windows 95
or Windows NT.

2.2 Software Installation, READS166

Place the CD-ROM in your drive. Go to the Rigel Products | 166 Software | READS166 | .exe
program. Click on the exe file and the program will begin to load in your system.
Follow the standard install directions answering the questions with the appropriate answers.

2.3 Third Party Software

A variety of third party software is available on Rigel’s CD-ROM. The software may be found in
the Strategic Partners Folder under Keil, Tasking, and PLS.

Data sheets on the IC’s used on our boards may also be found on Rigel’s CD.

Please note that software updates occur frequently. Please check our web
site (and the third party vendors web sites) occasionally to make sure you
have the most recent versions of the software.

3 START-UP

3.1 Connections, Jumper Settings

1. Connect your RIGEL board to the PC host via a serial cable.

2. Connect the board to a power supply.
The red LED will come on if power is connected correctly

3. Check to make sure jumpers are the correct position. There are two jumpers, one in
position P0.4 the other in P0.6. This is the default configuration for the RMB-167 and the
board will be populated this way from the manufacturer.

3.2 Software Initialization

Run the READS166 host driver by selecting Start | Programs | READS166. You may also start
READS166 by double clicking on the READS166 short cut icon if installed.

3.3 Serial Number

3.3.1 Demo Version

When you run the READS166 software a pop-up registration box will open asking for your serial
and customer numbers. If you are using the demo
version of the software you may press CANCEL
and the box will disappear and the About Box will
appear. Press the OK button in the About Box and
the software will run in the Demo mode. The demo
mode limits the size of the files you can compile to
about 8K.

3.3.2 Full Version

If you’ve purchased the READS166 software a
registration sheet with the serial number and customer number will be included with the
READS166 User’s Guide. When you run the READS software insert these numbers in the correct
boxes, press OK and then press OK in the About Box. Your software is registered and ready to
use.

3.4 Configuring READS166 and Initiating Host-to-Board Communicati ons

1. Press the Projects | Options | Project Properties | HW Configuration to select the
board you are using from the list. Or using the Tools | Hardware Configuration menu
command, choose the name of the board you are using from the board list which appears.

- -4

2. Open the TTY window using the Tools | TTY menu command. Select the communication
port parameters using the Tools | TTY | TTY Options menu command. You will need to
select the COM port you are using, and the baud rate.

3.5 Bootstrapping

In the default configuration, all monitor programs are downloaded to the boards after the boards
are bootstrapped. That is, there is no ROM on the board that is executed upon reset.
Bootstrapping loads a small monitor, called MinMon, which in turn loads a larger monitor
