1) ABOUT THIS FAQ


1.1) Who put this FAQ together?


    I started by putting together a FAQ on the 8051 microcontroller in
    response to my own frustration in finding information.  The FAQ has
    now been out for some time and has been very well received.  One of
    the questions that I'm frequently asked is if I know of a FAQ on the
    68hc11.  Not only that, but how many times have you seen the
    following questions posted on the newsgroups:  "anyone know of a C
    compiler for the 68hc11?", "anyone know of an assembler for the
    68hc11?", and so on.

    Therefore, I decided to jump in and try my hand again.  I figured
    that this would be a good learning experience.  From what I've seen
    so far, the 68hc11 is a good chip, and well worth learning and
    developing with.  I really don't have any experience with the 68hc11
    (yet), so I'm going to need everyone's help on this.  Just as with
    the 8051 FAQ, with everyone's help this FAQ should turn out to be a
    pretty useful document.

    Very special thanks to Ping Huang and Thomas Koenig of the
    news.answers moderators team for all of their help.

    I certainly hope that those of you who know of interesting items for
    the 68hc11 will share with everyone by contributing to this list.

    If you are a manufacturer and have an anonymous ftp site available
    that supports the 68hc11, please let me know by Email so that I can
    add it to this FAQ.  Also please feel free to keep me updated on your
    products.


1.3) What newsgroups will this FAQ be posted to?


    This FAQ will be posted to the following newsgroups:
          comp.realtime
          comp.robotics
          sci.electronics
          comp.answers
          sci.answers
          news.answers
    The first three newsgroups often contain discussions, announcements,
    or information on the 68hc11.  Check them out from time to time.  By
    posting to the *.answers newsgroups, the FAQ will automatically be
    archived.  The archive name of this FAQ (also included in the header)
    is: microcontroller-faq/68hc11.

    The schedule for posting will be once a month.  I can't promise that
    it will be on time, but I hope to post it on the 26th of each month.

    You might also want to check out the following newsgroups, since they
    occasionally have items of interest for you 68hc11 users.
          comp.sys.m6809
          comp.sys.m68k
          comp.lang.misc
          comp.arch.embedded
          alt.comp.hardware.homebuilt

    A bit farther afield, but still of possible interest:
          comp.ai.fuzzy
          comp.dsp
          sci.engr.control
          sci.engr.semiconductors


1.4) May I post this FAQ to my local BBS?


    I am putting no restrictions on the use of this FAQ except - It must
    be distributed in its entirety with the copyright notice, and no
    financial gain may be realized from it.  After all, I have spent, and
    continue to spend, a lot of time on this, and the only thing that I
    intend to gain from it is more information on the 68hc11, and getting
    to know my fellow 68hc11 groupies better.

    For this reason I have appended a copyright statement to the end of
    this FAQ.  I feel pretty silly doing this, but I just want to protect
    myself.  The copyright does not limit the use of this list for
    noncommercial purposes.  I hereby give my permission to one and all
    to pass this list around and post it wherever you want - as long as
    it is not for financial gain.

        Thank you.


1.5) How about FAQs on other microcontrollers?


    If anyone wishes to start a FAQ on another microcontroller, please
    feel free to copy the format of this FAQ - I don't intend on
    copyrighting the look and feel ;-).  With a common format, we will
    all benefit when trying to find information on a particular
    microcontroller.

    If anyone has any comments on the format itself, I'm open for
    suggestions.

    Two useful articles are also available.  One article provides a
    tabular cross reference of features and pin counts.  The second
    article provides pinout diagrams of many of the Motorola line of 8
    bit microcontrollers.  Both lists were compiled and are being
    maintained by Roger Nelson .

    For more information on various microcontrollers and their features,
    refer to the Microcontroller primer and FAQ listed above.
