This is a draft FAQ as an attempt to collect/distribute information
about the ST6 microcontrollers of SGS-THOMSON Microelectronics
on the USENET.

If this document will be accepted by the appropriate NewsGroups and
also approved by "news.answers" NewsGroup, we will call this document

"ST6 microcontrollers FAQ" (in short "ST6-FAQ").

For all those who care about French chauvinism:
Ask your SGS-THOMSON representative/distributor for ST6-ICs
produced outside France.

--------

The main purpose of this "FAQ" is to trigger a joint-venture
of collecting valuable - at least useful - information about the
ST6xxx family of microcontrollers introduced by SGS-THOMSON.
So please do not expect very much from this draft - we are still
at a starting phase. We'll work on it - and hopefully some of you, too.

If you take a look at the "Table of Contents'" last (status) column,
you'll notice: there are several gaps left at the moment and a lot
of question marks.

The initials there stand for persons who try to take care for
maintaining and filling some chapters of this FAQ draft
(see sub-chapter "How can I contribute to this FAQ?" for explanation
of these "aliases" );
it also indicates sub-chapter's status and date of last change.

The special characters adjacent to the shorthand "aliases" mean:

? request to care for,
! cares for (at least momentarily),
% topic is in process, but more information is needed
* topic is (said to be) finished
+ topic is updated

--------

#0.9) Trademarks LS%

Probably these are trademarks:

MS-DOS,
WINDOWS by Microsoft Corporation;
OS/2,
PC,
PC-DOS by International Business Machines Corporation;
ST6,
ST6xxx by SGS-THOMSON Microelectronics GROUP OF COMPANIES.

###1) ABOUT THIS FAQ LS*

#1.1) Who put this FAQ together? LS*

Based on the pre-work of the authors of

Microcontroller-FAQ/Primer,
68HC11-FAQ,
8051-FAQ Russ Hersch <si...@datasrv.co.il>,
COP8-FAQ Robin Getz <rg...@esd.nsc.com>,
PIC-FAQ Tom Kellett <t...@takdsign.demon.co.uk>

this proposal ST6-FAQ was initiated by

Emilio Caggiano <cagg...@vm.csata.it> (*EC*),
Jerry van Kampen <jvka...@worldaccess.nl> (*JvK*),
Leonhard Schneider <ub...@rz.uni-karlsruhe.de> (*LS*).

We decided to take the format and whatever was reasonable to be
taken from the for-runner FAQS (with permission of the authors).
The unique "#" character in front of the chapter numbers we put there
to ease forward/backward skipping using search commands.

To link an HTML version of this FAQ to his "ChipDir" was an idea of

Jaap van Ganswijk <gans...@xs4all.nl> (*JvG*).

Another HTML version of ST6-FAQ is kept by

Filip Gieszczykiewicz <fi...@alpha.smi.med.pitt.edu> (*FG*).

--------

#1.2) How can I contribute to this FAQ? LS%

If you have any suggestions or additions, or you would like to
correct any of the information contained herein, please eMail a note,
depending on subject, to *one* of the "co-maintainers"
(see status column in "Table of Contents"):

Emilio Caggiano <cagg...@vm.csata.it> (*EC*)
Jerry van Kampen <jvka...@worldaccess.nl> (*JvK*)
(place [Jerry] in subject line)
Leonhard Schneider <ub...@rz.uni-karlsruhe.de> (*LS*)

For the ease of FAQ maintaining we ask supporters to provide their
contributions in a format that matches the format of this FAQ.

Please precede your article by

a copy of the adequate topic line,
a subject line describing the contents of your article in brief,

and append

a line with your name and eMail-address.

Articles offered to the maintainers of this ST6-FAQ must be free
to be published on The Net.

If you give names of ftp/html-sites, please use URL conventions (rfc1630),
even if WE didn't do it by accident (but please point to our mistakes=
).

We certainly hope that those of you who know of interesting items for
the ST6 will share with everyone by contributing to this project.

If you are a manufacturer and have an anonymous ftp site available
that supports the ST6, please let us know by Email so that we can
add it to this FAQ.

--------

#1.3) What Newsgroups will this FAQ be posted to? LS%

This FAQ will be cross-posted to the following newsgroups:

comp.arch.embedded Embedded computer systems topics.
comp.realtime Issues related to real-time computing.
comp.robotics.misc All aspects of robots and their applications.
sci.electronics Circuits, theory, electrons and discussions.

Items will be posted once a month. We can't promise that it will be
on time, but we hope to post it on the *6th* of each month.
Easy to remember, isn't it: ST6 at 6th?

You may also want to check out the following newsgroups, since they
may occasionally have items of interest for ST6 users.

alt.comp.hardware.homebuilt
alt.lang.asm
comp.lang.misc

And probably later (*), depending on what people think....

comp.answers
news.answers
sci.answers

Archive (*): rtfm.mit.edu : <plus all mirror sites>

/pub/usenet/comp.answers/microcontroller-faq/ST6
/pub/usenet/sci.answers/microcontroller-faq/ST6
/pub/usenet/news.answers/microcontroller-faq/ST6

The national groups may be informed by short announcements
whenever there is an update-posting of the ST6-FAQ:

de.comp.sys.misc *LS*
de.sci.electronics *LS*
nl.comp *JvK*

The first four newsgroups often contain discussions, announcements,
or information on microcontrollers. Check them out from time to
time. Later on, by posting to the *.answers newsgroups, the FAQ will
automatically be archived. The archive name of this FAQ (also
included in the header) is supposed to be:

microcontroller-faq/ST6.

--------

#1.4) May I distribute this FAQ or post it somewhere else? LS*

We are 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, we have spent, and
continue to spend, a lot of time on this, and the only thing that we
intend to gain from it is more information on the ST6, and getting
to know fellow ST6 groupies better.

REMEMBER ! If you choose to upload this FAQ to any BBS or ftp site,
then *YOU* are responsible for updating it regularly.

###2) ABOUT THE ST6-FAMILY OF MICROCONTROLLERS JvK?

#2.1) The ST6xxx Microcontrollers SGS?

ST62 subfamilies are:

ST621X,
ST622X : Small general purpose with AD converter
ST626X : Small general purpose with AD converter, PWM and EEPROM
ST624X : LCD driver
ST628X : Dot matrix driver

ST63xx family is used for TV applications.

ST62xx and ST63xx families have the same, small instruction set.

--------

#2.2) Common / New ST6 variants SGS?

Common feature of ST62 devices is the high noise immunity. It enables
the designer to design an application without spending much time on
adjusting capacitors, shieldings, ground ... See Application note
AN435 in the ST62 General Purpose Application Manual for more detail
on this point.

New ST62 devices are under development in order to extend the
family downward and upward. Information on these devices will be
published later.

ACTUM REALIZER
Software Aided Computer Engineering for ST62 8-Bit
Microcontrollers, MS Windows 3 Edition: ST6-REALIZER/PC

The software allows to generate the program code with the following
steps:
- You draw the schematic circuit of the application with the symbol
available in the graphic system instead to writing the assembly code.
- Check the integrity of the graphical description, verify I/O
assignment etc. with the Analize Menu.
- The software develops automatically the program code and all files
related to the ST62 target.
- The Simulate Menu allows to monitor the signals of the application,
directly on the graphical description without to build hardware for
debugging.

Note: In the SGS-THOMSON BBS (see item #3.3 - Grenoble BBS) it is available
the Demo-Realizer Pack software and some application notes as
the AN676 and AN677 with this tool.

#6.7) Hardware Hints and Tips

TEST pin - JvK

Always connect the TEST pin to ground; in the manual an on-chip
pull-down resistor is mentioned, but in fact it is not there or
it simply does not function correctly.

ST62 EPROM TEST/VPP Pull-down Resistor - EC

From SGS-THOMSON BBS (see item #3.3 and #4.2) it is possible
to read the following Application tip n. 34:

Agnes Cacciaguerra, Rousset
Thibault Brunet, Rousset:

EPROM members of the ST62 MCU family use the pin labelled TEST on the
equivalent ROM-based ST62, but with the additional function as the
input for the programming voltage, VPP, for the EPROM.
Normally for the ROM devices the TEST input has an internal pull-down
resistor allowing the device to have this pin not-connected in the
circuit, while preventing unauthorized access to the TEST functions.

Several members of the ST62 EPROM based devices have been found to NOT
have this pull-down resistor on the VPP/TEST input of the devices. This
may cause a malfunction of the system or high current consumption of the
device if the TEST input is allowed to float high.

For this reason VPP/TEST pin must not be left open. It is advised to
connect this input to Ground via a resistor of 50k to 100kOhm.

This applies to the devices shown in the following table for devices
currently available. All future devices will have this pull-down
resistor.

Table of ST62 Devices with/without Pull down resistor on the VDD/TEST
pin:

PULL DOWN
Technology AT VPP

ST621X/2X 1.5=E6 Yes (see note)
ST62E1X 1.5=E6 No
ST62E2X 1.5=E6 No

ST6225 1.2=E6 Yes
ST62E25 1.2=E6 Yes

ST6240 1.5=E6 Yes
ST62E40 1.5=E6 Yes

ST62E94 1.5=E6 No
ST6294 1.2=E6 Yes
ST62E94 1.2=E6 Yes

ST628X 1.5=E6 Yes
ST62E8X 1.5=E6 Yes

All New ST62 1.2=E6 Yes

Note: All ROM Codes dating after July 1992 have used the revised mask
set, unless otherwise specified by the customer. In detail this applies
to devices with the SGS-THOMSON specified ROM code identifier greater
than SP, (excepting PK, SL and SN).

ST6 ROM code identifiers are used to replace the /XX part of the sales
type to specify the customer ROM code used. The sequence has been for two
alphabetic letters incrementing in alpha order (i.e. AA-AZ, BA-BZ etc).
From code YS however, ROM code identifiers have been restarting in an
alpha/number sequence (i.e. A0-A9, B0 to B9 and so on).
Check your part number (specified on the order, as, if custom marking has
been requested, the part number may not appear on the package itself) if
you wish to be sure. In case of doubt, contact the local SGS-THOMSON
marketing person.

What you have to keep in mind when switching between EPROM/OTP/ROM
Versions 951130 - EC

The ST62EXX microcontroller type is the EPROM version of this family.
They are intended for use during the development of an application
or for pre-prodution and small volume prodution.

The ST62TXX OTP type (One Time Programmable) have the same
characteristics of the EPROM except that they cannot be erased.
From the user's point of view, once programmed, the OTP and EPROM types
have exactly the same software and hardware features as the ROM version,
except for the following parts:

- No internal pull-up resistor available on pin NMI;
- No internal pull-up resistor available on pin Timer.

But also see article "ST624X ROM BANKING ALERT"
in chapter "Software Hints and Tips"

EPROM erasing - EC

The EPROM may be erased by esposure to the Ultra violet light.
The erasure of the EPROM begins when the memory is exposed to light
with a wave lengths shorter than approximately 2700 A.
The SGS-Thomsom recommmends an exposure to short wave ultraviolet light
which have a wave-lenght of 2537 A. The integrated dose (UV intensity by
exposure time) for erasure should be a minimum of 15 W sec/cm2.
The erasure time with this dosage is approximately 15 to 20 minutes
using an ultraviolet lamp with 1200 microW/cm2 power rating.
The life of the EPROM is reduced if the exposure is over 50 minutes
The devices should be placed within 2.5 cm of the lamp tubes during
erasure.

USING ST62XX I/O PORTS SAFELY - EC

The application notes AN432 by J.Stockinger on the SGS-THOMSON
Application Manual (1^ FREE Edition-January 1995) is very clear
for understanding the architecture of the I/O bit associated with
these port functions and provide additional indications on the
correct use of these features for functions as keybord scanning
and analog inputs.

--------

#6.8) Software Hints and Tips

Reset - Jvk

After reset is a good time to start the timer, configure the I/O
lines, and set up the data rom window register. Start your reset
routine by reloading the watchdog timer, and finish it with:

reti
nop

The Stack - DL

The stack is a hardware stack. This means that you are quite
limited in the number of calls that can be nested, as you have to
save some stack space for the interrupts.

Interrupts - JvK

Disable the A/D conversion interrupt as soon as
you enter the interrupt routines. The end of conversion state
is still valid after the interrupt routine ends and can generate
another interrupt request.

It seems that you would have to do the same with all other interrupts,
but I'm not quite sure, since I haven't had any problems with them.

The data window - DL

This is useful. I have used it when converting an A/D result
into a value to be compared with another A/D result. The required
calculation (multiply by 0.62) was a bit beyond the ST6, so I used
a 256 byte look-up table of the result.

You can set it up like this:
.w_on ; enable data rom window
.org 80h
.block 64-$%64 ; Force page boundary.
table
.byte 000h,004h,008h,00bh,00fh,013h,017h,01ah
.byte 01eh,022h,026h,029h,02dh,031h,035h,038h
.byte 0.............. ; etc...
ldi drwr,table.w ; The data rom window register is initialzed.

And to use it:
ld x, a2dresult
ld a, (x)

A/D Conversion - JvK

An A/D conversion takes about 70 microseconds for a 8 MHz crystal, not
70 milliseconds as printed in some databooks.
Only ONE I/O line can be programmed as an analog input line!

Getting the most out of the A/D converter - DL

The best accuracy is obtained by putting the ST6 to sleep, and
making sure that there has been no processor activity during the
conversion. Hence the use of two flags. All other interrupts
except the A/D interrupt set the ad_bad_flag. The A/D interrupt
sets the ad_good_flag if the ad_bad_flag has not been set.

a2d1:
clr adbadflag
clr adgoodflag
ldi adcr,a2don ; turn on set up and start a2d
wait
nop ; A TO D INTERRUPT HERE
ld a,adgoodflag
jrz a2d1 ; if not marked as good, do it again
; an untroubled conversion...

Note the nop after the wait. It is *important*.

Oversampling with the A/D - DL

Without wanting to go into any theory, you may increase the reliability
of your A/D conversions by sampling a few times and averaging. This
would present something of a computational challenge to the ST6, unless
you use a couple of tricks. Set up three locations thus:

ldi adbsum,00 ; bottom byte of result
ldi adtsum,00 ; top byte of result.
ldi adcount,16 ; NB this is a power of two

ld a,adbsum
add a,adr ; add result to sum
ld adbsum,a
jrnc a2d2 ; if carry, then add 1 to top byte
inc adtsum
a2d2:
dec adcount

jrz a2dend ; if adcount has rolled around, then quit
jp a2d1

After doing the conversion 16 times you have a total value that
you wish to divide by 16. This would be most easily accomplished by
a shift right [#:-} so instead we shift left into our adtsum thus:

a2dene:
jrz a2dfin ; z flag from ld above or dec below
ld a,adbsum
rlc a ; shift top bit into c flag
ld adbsum,a

ld a,adtsum
rlc a ; shift c flag into bottom bit
ld adtsum,a

dec v ; v loaded with number of shifts
jp a2dene

Here's an alternative method that I believe is significantly faster.

clr a
jrr 1,adtsum,a3s1 ; construct in accumulatoir using bit
; tests
ldi a,80h ; this is a 'divide by four' operation.
a3s1:
jrr 0,adtsum,a3s2
addi a,40h
a3s2:
jrr 7,adbsum,a3s3
addi a,20h
a3s3:
jrr 6,adbsum,a3s4
addi a,10h
............... etc..

If you like a good argument, find an appropriate Usenet newsgroup,
and suggest that this technique will allow you greater than eight
bits of accuracy... Only a few people on the net understand the
subject. And they can't be bothered to discuss it anymore, so the
whole argument is conducted by people who don't know what they're
talking about. Actually, that's just like every other thread.

Switching of I/O lines.

This must be done in the right order. At startup, I load them thus:

ldi dra,drabits ; set up I/O pins
ldi ddra,ddrabits
ldi ora,orabits

I have used copy registers for the data registers and option registers.
This is the sequence I settled on for changing an input to an output:

; SET PIN TO OUTPUT
ldi a,ddrabits

Usage of the Timer (Square wave, time measurements etc.) - JvK

Reliable periodic timer interrupt interval.
[under construction]

Square wave.

You can use the following piece of code inside your timer interrupt
routine:

jrr dout,tscr,lo_hi
hi_lo res dout,tscr
jp end_tim
lo_hi set dout,tscr
end_tim reti

The TIMER pin will switch value if a timer interrupt occurs. Be aware that
the value you set in the tscr register is provided to the TIMER pin the
*next* time the timer interrupt is generated.

Usage of the watchdog timer - JvK

The watchdog timer generates a general reset as soon as it has counted
down to zero from its starting value. Be aware and reload the watchdog
register periodically to prevent this. Do this within your main
code loop rather than from within a timer interrupt; as otherwise
you may have the ST6 crash without ever being reset, as the timer
interrupt / routine continue to work although the main code has stopped
working.

Long Jump Macros (useful macros to elongate the short jumping conditional
jump operation). Version 960130 - EC

What you have to keep in mind when switching between EPROM/OTP/ROM
Version 951130 - EC

Programming Mode:

The programming mode of the EPROM and OTP types is configured by
setting a voltage of 12.5 V to the Test/Vpp pin.

ROM option emulation:

On the EPROM/OTP devices it is possible to emulate the option mask of
the ROM devices by an "Option Byte" that can be programmed with the
programming tools.
This "Option byte" is automatically read and the selected options is
switched on.
Setting high the bit D7 of the option byte it is possible to prevent
(by hardware) the readout of the software contents.

ST624X ROM BANKING ALERT

From SGS-THOMSON BBS (see item #3.3 and #4.2) it is possible
to read the following Application tip n. 4:
Hans Reichmeyer, Grafing:

The ROM Bank switch Register RBSR of the ST6 family members with 8k of
ROM space has a difference in functionality between EPROM and ROM
devices.

The ROM bank switch register in ROM devices is NOT initialised during
reset and contains arbitrary information after power up. To addressa
page in the program address range from 0 to 7FF, the ROM bank switch
register must be loaded first.

The ROM bank switch register in EPROM devices IS cleared during reset
and addresses page 0 after power up.

A problem can arise if a user forgets to load RSBR in his software.When
the program accesses page 0 in an EPROM device, the device will behave
correctly (as RBSR is cleared at reset), whereas a ROM device will have an
undefined function... and will probably cause a program failure.

Thus it is mandatory to load RSBR before accessing the paged program
address region.

The family members affected are ST6240/E40.

Users of these devices should be made aware of this to prevent any
problem in the use of the ROM device after successful debugging with
the EPROM device.

#6.9) Miscellaneous Documentation EC!

From the SGS-THOMSON BBS (see item #3.3 and #4.2 EXAMPLES DIRECTORY
\Application tips\Atip.txt #22) it is possible to read the following
Programming Techniques:

ST6 GOOD PROGRAMMING TECHNIQUES 1.1
The ST6 Applications Team

Define all standard Registers for the device in a separate file:
Use same register names for all your applications
Include the file in your code with .INPUT directive

Use complete .DEF directives to name all your registers:
Makes a program more readable
Allows the Assembler to check for Read/Write errors

Clearly separate Code from Data in ROM:
Remember that .WINDOW simplifies access to data

Use X, Y, V, W Registers when possible to optimize code

Avoid use of SINGLE BIT instructions on I/O Ports and Write/Only Registers:
Remember to use shadow registers
Single Bit instructions are: SET, RES, JRS, JRR

Remember to initialise Reset and Interrupt vectors with JP instructions:
Use .SECTION 32 for vector addresses
Unused interrupts can be directed to a RETI instruction

Observe the correct sequences for modifying I/O port status:
Prevent unwanted interrupts

Put a RETI instruction at the beginning of the code:
IF you want to use interrupts later

Stop Timer, or clear Timer Interrupt in service Routine:
Prevent unwanted Timer interrupts

Remember to leave at least one instruction (e.g. NOP) after powering the
ADC:
Allow the ADC to settle before taking a reading

Set the Emulator Hardware/Software Watchdog jumper to suit the ST62:
Prevent Watchdog problems with ROM/EPROM/OTP ST62/HWD devices

Place commonly used subroutines in separate modules:
Can be used in many projects
No need to debug more than once
Document: function, variables[in,out,used] and stack level in header

Place commonly used code segments into macros:
Reduce stacking levels with in-line code
Create a Macro Library

Check on Stacking Level:
Prevent hardware stack overflow causing program fail

Always use .EQU directives to define constants:
Allows fast updating
Reduces the chance of leaving some values unchanged

Use .SECTION and not .ORG Assembler directives:
Make code relocatable, and portable to other applications
Let the Linker command line define absolute locations

Choose your symbol names appropriately and consistently

Use comments as much as possible:
The code may not be so clear at a later date, even tomorrow

Backup your files regularly:
Power cuts and other non-maskable interrupts can erase work in progress

Document all changes on a regular basis:
You may need to recover a previous state
or specify a Document Change Notice
