0)  Rantings and ravings

    Disclaimer:  Just so it is understood, the "rantings and ravings" are
    MY rantings and ravings.  My readers are refined and sophisticated
    and would never rant or rave.  I, on the other hand, sit in front of
    the TV in torn underwear and drink beer out of the bottle.


    Well gang, this should be my last post of the 68hc11 FAQ.  I'm
    turning this FAQ over to Bob Boys who never ceases to complain about
    my FAQs being more popular than his Motorola 68K FAQ.  Maybe he'll
    stop whining now :-).

    Seriously, I'm finding it harder and harder to find the time to do
    justice to my FAQs.  I'm afraid the 68hc11 FAQ suffered the most.
    That's where Bob comes in.  Besides being a first class beer drinker,
    he already has experience with FAQs (Motorola 68K and VME bus).  I'm
    sure that Bob will infuse much needed life into this FAQ.

    I thank all of you for your kind assistance and encouragement during
    the time I worked on this FAQ.  It may sound like a cliche, but the
    Internet is a great place to live.  I've met a lot of friends and I'm
    having a great time.  Someday, we'll all have to get together and
    drink some beer.  See ya around.


    Thanks to Motorola for sending me a set of their famous "pink books".
    This is a really great collection of reference material.  I wish that
    the manufacturers' literature for other microcontrollers (the 8051
    for example) was of such high quality.  These books are definitely
    not for the beginner, but if you are into the hc11, these books are a
    must.  A real first class effort on Motorola's part!


    The Imagecraft C compiler, ICC11 V3, is now shipping. It includes a
    Windows IDE with integrated editor, terminal program and the ability
    to operate compiler tools and options.  A make utility and library
    source are included along with the field proven compiler tools. Price
    $100. For more info, check out the Webpage http://www.imagecraft.com
    or Email to imagecft@best.com.


    Dunfield Development Systems has just released version 3.14 of their
    C development tools.  They also have a new web page and new email
    addresses:
      Web:   http://www.dunfield.com
      Email: General information:               info@dunfield.com

    Take care,

              Uncle Russ


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.


1.2)  How can I contribute to this list?

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.

2)  ABOUT THE 68hc11


2.1)  The 68hc11 microcontroller

    General

    The 68hc11 is a powerful 8-bit data, 16-bit address microcontroller
    from Motorola 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 ansynchronous communications
    channels (RS232 and SPI).  Typical current draw is less than 10ma.


    Architecture

    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.  Although an eight bit processor, the 68hc11 has
    some 16 bit instructions (add, subtract, 16 * 16 divide, 8 * 8
    mulitply, shift, and rotates).  A 16 bit stack pointer is also
    present, and instructions are provided for stack manipulation.
    Typically multiplexed address and data bus.


    Onboard subsystems

    Timer -  Main timer system comprises of a single 16 bit counter
    clocked at the E clock (2,3,or 4 Mhz - there is a programmable
    prescaler to slow it down if required). From this single counter run
    a number of input capture and output compare registers (3-4  IC, 5 -
    4 OC). The IC and OC functions are very versatile, and pulses as
    short as 1 E clock can be generated.

    A-D Convertor - Typically 8 channel 8 bit A/D, although the G5 has a
    10 bit A/D.

    Serial Communications Interface (SCI) - Asynchronous serial
    communications; Data format - 1 Start, 8 or 9 data, and one stop bit.
    Data rate - 150 - 312500 Baud (312500 is using 4 mhz E clock)

    Serial Peripheral Interface (SPI) - Synchronous serial
    communications, comprises CLK, DATA IN, DATA OUT and optionally chip
    selects.  As well as using specific SPI devices, it is very easy to
    expand IO using the SPI and standard logic devices (e.g. 74HC595 and
    74HC165).


2.2)  68hc11 flavors

    The following are Motorola flavors:

    HC11 A Series
       8K ROM (A8), ROMless (A0,A1), 256 RAM, 512 EEPROM (A1,A8), SPI,
       SCI, 3 IC 5 OC, 8 channel 8 bit A/D

    HC11 C0
       Nice new device developed together with AT&T.  ROMless, on board
       bank switching to support memory maps of up to 256K.  Totally
       glueless interface - Chip selects on board, Read Enable and
       Write Enable signals now generated on chip.  256 RAM, 8 channel 8
       bit A/D - Good pricing

    HC11 D Series
       Smallest and lowest cost member of the hc11 Family.  ROMless (D0),
       4K ROM (D3), 4K EPROM (711D3) - No A-D or EEPROM.  Still has
       standard timers and serial ports

    HC11 E Series
       Same as A series execpt 512 bytes RAM and 512 EEPROM (2048 for
       E2).  Pin compatible, only difference is one timer pin (PA4) can
       now be used for IC or OC instect of just OC.  Also have EPROM
       devices and larger memory - hc711e9 (12K OTP), hc711e20 (20K
       OTP)

    HC11 F series
       ROMless, non multiplexed address/data bus with 4 chip selects
       built in.  1K RAM, 512 bytes EEPROM - otherwise same peripherals
       as E series

    HC11 G Series
       16K ROM/EPROM, Non mulitplexed address/data bus, 512 RAM, 4
       channel PWM, 10 Bit A/D convertor, 2 separate 16 bit timers

    HC11 K4
       24K ROM/EPROM, 1Mb addressing using on chip memory mapping.  Non
       multiplexed address and data  bus. 4 programmable chip selects, 8
       channel 8 bit A/D.  4 channel PWM, 768 bytes RAM

    Toshiba second-sources the 68hc11, and they list the following
    variants: A0/A1/A8 and E0/E1/E9.

    For a nice breakdown of the 68hc11 line, check out the file
    taxonomy.txt at cherupakha.media.mit.edu : /pub/miniboard/hobby-tips.
    The file contains a table detailing all of the possible combinations
    that the 68hc11 is supplied in.


2.3)  Sources and prices

    Sources??  Prices??  Hell - you can't even find the suckers!  For
    those of you who remember the old Chicken Man series on radio, "He's
    everywhere! He's everywhere!" - the 68hc11 is not Chicken Man.  The
    68hc11 - "It's nowhere, it's nowhere!"  I remember one episode in
    which our hero was fighting against an evil plot to steal all of the
    refrigerator light bulbs in the world.  Well, maybe the same thing
    happened with the 68hc11 - they just can't be found.

    Maybe it's just a clever scam.  The 68hc11 really doesn't exist.
    Instead, Motorola cobbled together a microprocessor using an Intel
    8051 running an emulation of the 68hc11 instruction set (Intel
    Inside?).

    Ruud Schramp found some in the Netherlands (sounds like an
    appropriate place to find them).  The breakdown is as follows
    (1 US dollar =+- Dfl 1.70):
       Main Importer of Holland   Dfl 15.-- (quantity >100)
       Main Importer of Holland   Dfl 19.-- (if you buy 1 and if they
                                             want to sell 1)
       Distributor                Dfl 25.-- (also no single sales)
       Shop (Display Electronica) Dfl 35.-- (quantity 1)

    Also, the 68hc11 can be found at the following places:

       They list the 68HC11A1P (48 pin DIP version) at $11.95 in their
       1994 electronic component catalog (#37).  They have lots of other
       good stuff in the catalog.  No minimum order.

       Catalog number 112 indicates that the carry Motorola micros
       (including the HC11 family.  These guys are big distributors, so
       they can probably get any part in the HC11 family, but they
       probably won't be cheap.

       Prices shown in their 1992 catalog are:

       MC68HC11E0FN (PLCC version) lists at $21.26

       They usually have a couple varieties at good prices.


2.4)  Advantages realized in implementing control applications on this
      family of microcontrollers

    Traditional architecture - a more traditional architecture than other
    competing products (such as the 8051 and PIC) makes it easier to
    learn and develop on (especially well-suited for teaching
    microcontrollers)

    More features - a 68hc11 is typically a "one-chip" solution since it
    often includes such items as A/D, PWM, and many I/O lines

4)  68hc11 PRODUCTS

    This section includes descriptions and references to free and
    commercial software for the 68hc11.  FTP sites and BBSs contain many
    quality packages and code samples for free.  For heavy duty use, you
    might prefer the many commercial packages that are available.  Some
    very high quality, low-priced packages are available which are
    suitable for both the hobbyist and professional on a limited budget.
    With the public domain (or free) stuff, you're usually on your own.
    The commercial packages usually provide extensive documentation and
    support.


4.1)  Free languages and development tools

    The following is a list of the languages and development tools that I
    could find on the net.  Nearly all of them include source code,
    however not all are public domain.

    Assembler

      Program: asxxx-v1.51-beta.tar.gz
      Description:  This is an updated version of the ASXXXX
                    cross-assembler package written by Alan R. Baldwin of
                    Kent State University.  This version includes the
                    following changes:
                      - Port to Unix and Unix-like OS's
                      - Support for ar(5) style libraries in the linker
                      - Improved code area management
      Comments:  This is the assembler back-end currently used by the
                 Coactive Aesthics gcc port; a majority of these changes
                 were made to better support the gcc port.  The current
                 distribution is a drop-in upgrade for the version
                 currently used in the Coactive gcc port.
