A couple of notes: Unlike previous machines, there are just too many
resolutions to give each resolution a name. Therefore, I will do my best
to describe what the resolution is and which monitor it is on.
- NOTE: TV and a Color Monitor are the same.. by Color Monitor, I am
talking about the standard SC1224. By VGA, I mean a standard VGA
Monitor.

and lastly.. there are compability modes for ST Low, ST Medium, and ST
High on both VGA monitors and SC1224 monitors. (On a color monitor, ST
High is achieved by using the interlace mode).
Also, the ST Monochrome monitor (the SM124) will work with Falcon030 as
well. However, it only supports one resolution: ST High Resolution.
All modes on a TV can be overscanned. This means multiplying the X and Y
resolution by 1.2. For example, modes with 320 pixels of horizontal
resolution (X res) will become 384 pixels across, and modes with 640
pixels will become 768 across. Overscanning is done in the X and Y
resolution. You can't do them independently. Special Note: On a VGA
monitor, overscan is "faked".. since the video hardware doesn't have the
capability to do overscan on a VGA monitor, we made it so that if a
overscan mode is set on a VGA monitor, you still see the normal size
screen, but the screen is a window onto the bigger overscanned image.
Make sense? We did this for compatibility. This way if a game that has an
overscanned startup picture can use the same pic on both the VGA monitor
and the TV monitor. Pretty cool, eh? <grin>
BTW.. Overscan can NOT be set from the desktop. The AES and Desktop will
work just fine with it, but because you can't see the parts of the
screen, we thought that that option shouldn't be available from the
desktop. We don't want to confuse people. However, Overscan can be set
using a new XBIOS call (Vsetmode()).. so it is still available.
I hope I haven't made any mistakes. I triple-checked this document in
search of errors and I couldn't find any. If you do find some, send me
Email on GEnie (to TOWNS) or CIS (70007,1135) and let me know.

The smaller the number of times I have to type that message, the

After looking at this one more time.. one point to clear up: By
saying SC1224 Color Monitor, I mean any Color Monitor that Atari
have manufactured for the ST/Mega/STE/MegaSTE computers. Clear
as mud? ;-)

I found this file on the local ATARI Company's BBS : (original in Dutch)
This article is written by Wilfred Kilwinger (Support Manager) for Atari
Briefing, the newsletter by Atari (Benelux) B.V. for the Atari user
groups. It was specifically stated that it could be reproduced. I have
translated it in English with the assumption that an English translation
would be considered the same as the original.
The original also contained a description of all the features of the
Falcon
which have been reproduced here a zillion of times so I did not include
these.
Atari custom chips
VIDEL
The VIDEL takes care of the video functions of the system including
overscan, overlay mode and true color graphics.
COMBEL
The COMBEL is the system manager of the Atari Falcon030. This chip
controls all system functions. Also the BLITTER is built in in this chip.
SDMA
The SDMA is the Sound DMA and controls the sound part. We have built in a
unique matrix switch function in this chip (more details in the second
part)
KEYBOARD PROCESSOR
The keyboard processor has been improved and is now also suitable for
high resolution mice.
Besides the above custom chips the Atari Falcon030 has a number of
standard chips like the Motorola 68030 and 56001 DSP. Another
important chip is the CODEC in which the 16 bit AD and DA converters are
located.
Video modes
As you can see in the survey of Operating System calls the video hardware
is complete software controllable. The following combinations can be
chosen:
Mode Resolution Bit planes Colors Palette
ST LOW 320x200 4 16 4096
ST MED 640x200 2 4 4096
ST HIGH 640x400 1 2 4096
True Color 640x480 8 256 262144
320x200 15bpp 32768 N/A
The last mode asks for some explanation. Here there is no color palette
but 15 bits per pixel to describe the pixel itself. The format is
RRRRRGGGGGXBBBBB. VDI supports this mode thus programs that have not been
written for this mode specifically can use it nevertheless. X is the
overlay bit and can be used for video titling and special effects.
320x200 16bpp 65 N/A
This mode is called the slideshow mode, is not supported by the VDI, you
are on you own. X is an extra green bit.
True Color in 640x480 is not possible because of the bandwidth of VGA
monitors.
Mode Resolution Bit planes Colors Palette
VGA 320 of 640 1,4,8 2,16,256 262144 (Overscan
Video 200 of 400
With Video we mean the Atari SC-monitors, the TV modulator and/or the
composite video output.
All modes can be genlocked. With adaptors we convert the 15-pole video
bus to thee standard Atari or VGA connections.

Matrix coupling
To make the system performance in the audio part as good as possible
Atari designed a miniature 'telephone exchange' that can easily connect
the source devices to the receiving devices. Also it is possible to make
more than one connection at a time.

VIDEO SETMODE
int setmode( int modecode );
The setmode( int modecode ) call is used to place the Falcon/030 SHIFTER
into a specific mode. A bit-encoded value (called a "modecode") is passed
to setmode() to set the mode, setmode() returns the previous mode that
was set.
To help make the building of modecode values easier, here is a table of
defines:
#define VERTFLAG 0x100
#define STMODES 0x80
#define OVERSCAN 0x40
#define PAL 0x20
#define VGA 0x10
#define TV 0x0
#define COL80 0x08
#define COL40 0x0
#define NUMCOLS 7
#define BPS16 4
#define BPS8 3
#define BPS4 2
#define BPS2 1
#define BPS1 0
Using these defines, you can build a modecode for any possible mode.
For example:
For True Color Overscan:
modecode = OVERSCAN|COL40|BPS16;
For ST Medium Compatibility mode on a Color Monitor/TV:
modecode = STMODES|COL80|BPS2;
For ST Low Compatibility mode in PAL on a Color Monitor/TV:
modecode = STMODES|PAL|COL80|BPS2;
For 256 color, 80 column mode on a VGA monitor:
modecode = VGA|COL80|BPS8;
If you have a modecode and wish to know how many bits per pixel it has,
use the following:
if( modecode & NUMCOLS ) == BPS16 )
do_something_cool(); /* You have true color mode */
The setmode() call will return the previous modecode set. You must use
this value to get back to whatever mode you were in before you made your
setmode call.
int mon_type(void)
The mon_type() function will return the kind of monitor that is currently
in use. Here are the possible return values:
0 = ST monochrome monitor
1 = ST color monitor
2 = VGA monitor
3 = Television.
void ext_sync( int flag )
This function sets or clears external sync. If flag is set, external sync
is enabled. If flag is clear, then internal sync is used.
SOUND-calls
locksnd();
Used as a semaphore to lock the sound system. From other applications.
unlocksnd();
Used to release the sound system for other applications to use.
soundcmd(mode,data);
This command is used to get or set the following sound parameters.
If a negative number is used as the input then the current setting us
returned.
MODE OPERATION MEANING
O LTATTEN Sets the current left channel output
1 RTATTEN Sets the current right channel output
2 LTGAIN Sets the current left channel input gain.
3 RTGAIN Sets the current right channel input gain.
4 ADDERIN Set the output of the 16 bit signed adder to
receive it's input from the ADC, Matrix or
both.
5 ADCINPUT Set the input the the ADC. The input can either
be the left and right channel of the PSG or the
left and right channel of the microphone.
6 SETPRESCALE Used for compatibility. This prescale value
is used when the DEVCONNECT() internal
prescale value is set to zero.
setbuffer(reg,begaddr,endaddr);
This function is used to set the play or record buffers. REG selects
playback or record, while begaddr and endaddr are the buffers beginning
and ending locations.
(int) reg - (0) Sets playback registers.
- (1) Sets record registers.
(long) begaddr - Sets the beginning address of the buffer.
(long) endaddr - Sets the ending address of the buffer.
setmode(mode);
This function is used to set record or playback mode. The modes are as
follows:
MODE OPERATION
(int) 0 8 Bit Stereo
(int) 1 16 Bit Stereo
(int) 2 8 Bit Mono
settracks(playtracks,rectracks);
This function is used to sets the number of record or playback tracks.
setmontracks(montrack);
This function is used to set the output of the internal speaker to one of
the four tracks currently playing. The internal speaker is only capable
of outputting ONE track at a time.
setinterrupt(src_inter,cause);
This function is used to set which interrupt will occur at the end of a
frame. If the frame repeat bit is on, this interrupt is used to allow for
double buffering the playing or recording of sound. Interrupts can come
from TimerA or the MFP i7.
buffoper(mode);
This function is used to control the operation of the play or record
buffers in the sound system. The input to this function is a bitmap. If
mode is set t0 -1 then the current status of the buffer operation bits is
returned.
NOTE: The sound system contains a 32 byte FIFO. When transferring data
to the record buffer, software MUST check to see if the record enable
(RE) bit was cleared by the hardware. If the bit was cleared then the
FIFO is flushed, if not then software must flush the FIFO by clearing the
record enable (RE) bit.
dsptristate(dspxmit,dsprec);
This function is used to tristate the DSP from the data matrix.
gpio(mode,data);
This is used to communicate over the General Purpose I/O on the DSP
connector. Only the low order three bits are used. The rest are reserved.
This call, depending on the mode, can be used to set the direction of the
I/O bits, read the bits, or write the bits.
devconnect(src,dst,srcclk,prescale,protocol);
This function is used to attach a source device to any of the destination
devices in the matrix. Given a source device, this call will attach that
one source device to one or all of the destination devices. This call
also sets up the source clock and prescaler, protocol and protocol source
if used.
sndstatus(reset);
This function gets the current status of the codec.
buffptr(pointer);
This function returns the current position of the play and record data
buffer pointers. These pointers indicate where the data is being
read/written within the buffers themselves. This function is also used to
determine how much data has been written to the record buffer. See
buffoper().
The above is not yet complete. Atari has also routines for JPEG and andio
conversion.

Things which the 56001 should be useful for include software sound
synthesis & matrix*vector multiplication (the basis of 3D vector games).
If the DSP DMA is implemented right (does anyone have a programmer eye
view of this yet?) is should be possible to use it as an extremely fast
graphics processor for polygons/phong shading/texture mapping (I wonder
if anyone will bother to write an "Ultima Underworld" type game for the
Falcon?). I worry about this though - the DSP is 24 bits and the 68030 is
32 bits so there's plenty of room for Atari to screw up...
For anyone who hasn't seen the latest AEO, the Falcon appears to have
been design as a 24 bit computer, partly to maintain compatibility with
existing software. This doesn't mean third party boards etc can't extend
that, but it explains the 14 meg memory limit. The other captures from
Jim Allen posts to GEnie say that the Falcon chips all seem to talk at
16mhz. Another poster mentioned here that there's an 8bit processor to
dsp channel, I guess for uploading code into the dsp, though I don't know
if that means you can't tell the dsp to load a program from a memory
location itself, which would be faster, I'd guess.
Motorola says the top speed the 56001 is clocked at is 33mhz, so the
AD/DA converters must be the parts clocked at 50mhz.

clint@artech.UUCP (Clinton Keith) writes:
The adc/dac channel is driven off the DMA clock, which is driven off a
sub-divided horizontal scan rate. The 525 scan line rate sub-divided by
12, 24, 48 and 96 give the 6250, 12500, 25000 and 50000 bytes per second
DMA/CODEC rate. This is the same as the STE/TT.
In the very techie "test" of the Falcon in the German C'T you can read a
different story:
"[external/internal clock, prescale 4-24 or 128]. Internally there is a
27.175MHz clock to select the STe known sampling rates of 12.5KHz, 25KHz
and 50KHz, or 32MHz in order to use the full bandwidth of the memory
transfer, with an sampling rate of 62.5KHz on eight 16bit channels. This
is also the upper limit for the external clock."
(If the above doesn't make any sense then it is probably because my
German is even worse than my English)
