About Freescale Microcontroller

Sunday, November 30, 2008

This page described a multi-pass code-seeking disassembler for the Motorola 68HC11 and other compatible processors includig the 6800, 6801, 6802, 6803, etc.
It includes a number of features to enhance the readability of traditional disassemblies.
It has been used by the author for various applications including disassembling GM (including Holden) vehicle ECMs.

The 68HC11 is a powerful 8-bit data.
16-bit address microcontroller from Motorola (Now Freescale) with an instruction set that is similar to the older 68xx (6801, 6805, 6809) parts.
Depending on the variety, the 68HC11 has built-in EEPROM/OTPROM, RAM, digital I/O, timers, A/D converter, PWM generator, and synchronous and asynchronous communications channels (RS232 and SPI).
Typical current draw is less than 10mA.
Optimized for low power consumption and high-performance operation at bus frequencies up to 4 MHz.
The CPU has two 8 bit accumulators (A & B) that can be concatenated to provide a 16 bit double accumulator (D).
Two 16 bit index registers are present (X & Y) to provide indexing to anywhere in the memory map.
Having the two index registers means the 68HC11 is very good for processing data.

This project designed by Mr.Karl Lunt.
This PC-based bootloader was written in 1995 for loading S19 records into most 68hc11 variants.
The program was written in Microsoft C and uses a COM port to talk to the target.
It's providing both the source file (bootload.c) and the executable (bootload.exe).
The source file needs no extra .h files other than those already available in the Microsoft set.

Great price/performance.
Non-intrusive real time emulation.
Connects to PC serial port.
Hosted by any computer with a serial port.
Software and Hardware breakpoints with 16 bit pass counter.
User reset with breakpoints active.
Automatic clock speed switching for better very low speed emulation.
Wide variety of emulation probe types makes device specific configuration easy and cost effective.
Accepts Motorola S-record and Intel Hex format object code files.
Protective housing with power supplies built in.
Unlimited free technical support.

The programming interface allows you to write a program, compile it, download it, and debug it.
The program can be written in assembly language, Basic, or C

This guy make a prototype Electronic Throttle Controller as his final year project at CPIT.
The system consists of a 68HC11 based main board.
A stepper motor and driver board.
A pedal position sensor and an engine speed sensor.
An Electronic Throttle Controller replaces the mechanical linkage between a cars accelerator pedal and throttle.
Breaking this linkage frees the designer to allow inputs from systems other than the drivers foot to control engine speed.
Such a system can be used in launch/traction control systems, gearbox controllers and anti-stall systems.

This software lets you write and test assembly language programs for the Motorola 68000 processor.
The program is designed to lets you edit, assemble and simulate 68000 programs in a Windows environment.

This tutorial also available in zip file.
Target of the audience is for beginners, internediate and advanced user.
There are brilliant guys there with many are really good at asm programming and have lots of experience which you can ask if have a problem.
