This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDLversion 1. ARM architecture Revolvy Brain revolvybrain. An exhaustive list of every instruction would prove to be quite cumbersome, so I will display freescaale a few of the basic instructions. It is the successor to the Motorola and is succeeded by the Motorola Development of the EPROM memory cell started with investigation of faulty integrated circuits where the Views Read Edit View history.

Freescale 68HC11 – Wikipedia

Motorola series topic The Motorola 68h11 also termed x0, m, m68k, or 68k is a family of bit CISC microprocessors. Each port is eight-bits wide except for D, which is six bits in some variations of the chip, D also has eight bits. The exception stack frame is different.

See the presenation area for more details. A bit register can store different values. How to use 68hhc11 documentation. The block size was variable, so it was usually used for segment-based memory management.

QCard Users Guide

It does, however, handle an address space of bits from 0x to 0xFFFF. It has two eight-bit accumulators, 68hc111 and B, two sixteen-bit index registers, X and Y, a condition code register, a bit stack pointer, and a program counter. Finally, A Turnkeyed C Application Program introduces a real-time interactive application, and provides code you can use as a template for your application. This page is about: Originally introduced in the mids, the architecture is an enhancement of the Freescale 68HC The core is the first multithreaded core designed by Freescale and reintroduces an enhanced version of AltiVec to their products.


With external memory, B and C are used as address and data bus. The April issue of Oh! Member feedback about Index of computing articles: While every precaution has been taken in the preparation of this manual, Mosaic assumes no responsibility for errors or omissions, or for damages resulting from the use of the information contained herein. You can place values into and read values out of D without ever having to explicitly call A or B, which is why it is this phantom ‘pseudo’ register.

The term was used to describe microprocessors, and other complex integrated circuits, which use 68uc11 smaller manufacturing processes, producing more transistors per area.

Motorola’s 68HC11x Family of 8-bit Micro-controllers

In some cases, replacing th The modules of the microcontroller were designed independently and released as new CPUs could be tested. This family has five CPU registers that are not part of the memory: While instructions are processing, certain flags raise, might change, or otherwise make no change. The QCard is intended for use by experienced programmers up to freezcale challenge of real-time programming.

For those who are designing “turnkeyed” instruments, we have included a complete turnkeyed application program. Initial implementations used a 0.


An optional real-time clock tracks the calendar and time of day and battery-backs the K RAM. FM, a Japanese magazine for Fujitsu personal computer users, contained the first description of the ‘s additional capabilities. Each port is eight-bits wide except for D, which is six bits in some variations of the chip, D also has eight bits. Instruction set architectures Revolvy Brain revolvybrain.

The appendices contains detailed specifications, pin-outs, and schematics:. Other registers of interest are the two bit registers IX and IY.

Not Approved for Life-Support Use. In Apple Macintosh computers, the was introduced in the Macintosh Quadra, which was named for the chip.

Science-related lists Revolvy Brain revolvybrain. The Freescale 68HC16 microcontroller family is intended as a bit mostly software compatible upgrade of the 68HC Without thewe would be referencing a memory location. The 68HC11 processor is an 8-bit databit address micro-controller.

Animal common name disambiguation pages Revolvy Brain revolvybrain. The 68HC11 is upward compatible with the processor with an addition of the Y index register.

The original introduced in had a bit address bus and a bit data bus. Programming Model Programming Model, showing register layout. I provide more examples in my presentation. Contact us for technical help or just to chat. The paging scheme used allows for a theoretical maximum of 4MB of flash.

An Introduction to Multitasking.

Because of its smaller data bus, it was only about half as fast as a of the same clock speed.
