Preparing the ICE10 System for Use
For successful operation, the ICE10 must be connected and configured correctly. This
section explains how to connect the system, and how to determine which Pod to use to
successfully emulate a specific AVR part.
2.1 General
Hardware
Description
Figure 2-1 shows a simplified block diagram of the ICE10 connected to a target board.
Once the emulator is connected and configured correctly, it will behave like the emu-
lated device, and allows easy prototyping and debugging of applications in real-time.

AVR Studio. Configuration of this device is controlled and done directly from AVR
Studio.
Figure 2-3. ATtiny15POD
Figure 2-3 shows the ATtiny15POD which should be used when emulating the ATtiny15
device. The Pod provides a buffer protecting the emulator unit. In addition, the
ATtiny15POD contains a 4-channel 10-bit A/D converter with one differential input with
optional gain stage. This Pod is configured from AVR Studio, no manual jumper settings
are required.
Figure 2-4. AT90ADCPOD
Figure 2-4 shows the AT90ADCPOD which should be used for a wide range of AVR
devices. This Pod must be configured manually with jumpers for correctly operation.
Configuration of the AT90ADCPOD is described in Section 4, and is also available as an
interactive configuration walkthrough in the on-line AVR Studio help system.
There are different Probe cables supplied with the ICE10 emulator. Only one pod, and
one probe cable should be used at any given time, and the pin count and shape of the
probe should match the device being emulated.
When using the ATtiny15POD only, the 8-pin DIP Probe can be used. When Using the
AT90ADCPOD, use the appropriate Probe for the device being emulated.
Preparing the ICE10 System for Use
AVR® ATICE10 User Guide 2-3
2.2 Connecting
ICE10 to PC
The ICE10 connects to any PC through a standard RS-232 port (COM port). Connect
the RS-232 Cable between the ICE10 and any free COM port on the PC. AVR Studio
will automatically search through all available COM ports and detect the emulator.
Note: If there are other devices taking control over the COM ports, these have to be
shut down before starting AVR Studio. AVR Studio cannot force control over a
COM port if other resources have control of the port (e.g., Modem, IrDA, PDA,
etc.)
2.3 Connecting
ICE10 to Target
Board
Depending on which AVR microcontroller should be emulated, either the ATtiny15POD
or the AT90ADCPOD should be connected to the Pod connector on the ICE10. Table 2-
1 shows which Pod to use.
In short, the ATtiny15POD should be used for ATtiny15 only. The AT90ADCPOD is
used for all other listed devices.
2.4 Jumper Settings The configuration system on the ATtiny15POD and AT90ADCPOD is different. The
AT90ADCPOD uses jumpers that need to be placed manually on the Pod. The
ATtiny15POD uses a jumperless system where all configuration is done directly from
AVR Studio. For in-depth information about AT90ADCPOD jumper settings see Section
4.
2.5 Connecting
Power
The ICE10 system has an internal power regulator that delivers 15W at 5V. The ICE10
itself uses about 10W. The power supply delivered with the ICE10 is dimensioned to
meet the requirements of the emulator. If another power supply is used, it should supply
a voltage between 9 and 15 VDC and a minimum of 20W. The battery eliminator con-
nector on the ICE10 system is a standard type with 2.1 mm center tap. Ground should
be connected to the center tap.
Note: The target application power must not be present when the emulator is turned
off, as this may cause damage to the pod.
2.6 Summary Complete the following procedure in order to start using the ICE10. Before connecting
the probe cable to the user application:
Connect the RS-232 cable between the ICE10 unit and the PC serial port.
Connect the correct pod card to the ICE10 unit with the supplied pod cable.
Connect the correct probe cable to the pod.
Make sure that the pod settings (jumpers) on AT90ADCPOD are set according to the
requirements.
Connect the enclosed power supply (9 - 15 VDC) to the ICE10 unit.
Turn on the power and check that the red LED marked POWER is lit.
After a short time (<10 s), the green LED marked READY will be lit and the ICE10
system will be ready.

AVR® ATICE10 User Guide 3-1
Section 3
Using the ICE10
This section will cover main features and considerations when using the ICE10 and AVR
Studio to emulate AVR devices. AVR Studio is a professional front-end for both high-
level and assembly level debugging. If no In-Circuit Emulator is connected AVR Studio
will start up as a stand-alone simulator. AVR Studio is described in the on-line help sys-
tem in AVR Studio, and should be studied carefully in order to take full advantage of all
available options and features.
3.1 Installing AVR
Studio
To install AVR Studio insert the supplied Atmel CD-ROM in the computer and navigate
to “Products -> AVR 8-bit RISC -> Software”. Right click with the mouse on the
“astudio3.exe” file and select “save link as”. Select an empty directory and save the file.
Execute the “astudio3.exe” file. This is a self-extracting file that will extract all required
files to the current directory. Execute the “Setup.exe” file. This will guide you through the
setup process.
Note: AVR Studio version 3.5 or later is required for ICE10 support.
3.2 Emulating with
ICE10
It is assumed that the reader has general knowledge of how to use the AVR Studio soft-
ware. This section will focus on features and considerations applicable to the ATICE10
emulator.
3.2.1 Initial Setup Before emulating with the ICE10, the emulator, pod and probe must be connected and
configured correctly. This is described in Section 2.2 to Section 2.6 and Section 4.
3.2.2 Starting AVR Studio When the system is correctly connected and powered up, AVR Studio should be
launched. AVR Studio will look for any supported tool connected to the COM ports. Note
that AVR Studio searches through the COM ports in a sequential manner. If other Atmel
tools are connected to the COM ports, make sure that these are switched off, or discon-
nected, as AVR Studio will look for any supported tool, and connect to the first tool it
finds.
Note: Make sure no other applications have control of the COM port that the ICE10 is
connected to.
3.3 ICE10 Emulator
Options
When the emulator is started with a new project the “Emulator Options” dialog will
appear. This dialog determines how the emulator behaves.
Note: The emulator options dialog box (Options → Emulator Options) will not be
available before a project has been loaded and the emulator has been detected
by AVR Studio.
Using the ICE10
3-2 AVR® ATICE10 User Guide
3.3.1 Device Depending on which device is selected, unavailable options will be grayed out. A grayed
out option indicates that this option is not applicable for the selected device. The
ATtiny15POD is completely configured by this emulator options dialog. The
AT90ADCPOD requires additional jumper settings to complete the configuration as
described in Section 4.
3.3.2 Clock Source When using the AT90ADCPOD three clock source options are available. The
AT90ADCPOD can use one out of three available clock sources; the programmable
internal clock in the ICE10, a crystal or an external oscillator in the user application. The
ATtiny15POD only uses the internal clock option.
3.3.3 Internal Frequency The internal clock can be adjusted between 400 kHz and 20 MHz. Any frequency within
this range can be selected, and will be produced with an accuracy better than 200 PPM
for most frequencies. In addition jumpers needs to be configured on the AT90ADCPOD
as described in Section 4.
3.3.4 External Range When external clock source in the user application is used, this must be in the range
between 32.768 kHz and 10 MHz. To use an external clock source, select External
Oscillator in the menu. When using external crystal, it is important to select the proper
range in the External Range menu to make the clock system work properly.
Note: Make sure the jumper settings on the AT90ADCPOD are set according to the
options selected in the Emulator Options menu.
3.4 Emulator
Configuration
System
The ICE10 has room to store 6 different devices in the Emulator unit Flash memory.
Using the AVR Emulator Configuration system found in AVR Studio (Tools -> ICEPRO/
AVRICE/ICE10 Configuration system), it is possible to select which device that should
be downloaded to the emulator. Only devices downloaded to the emulator can be emu-
lated. Figure 3-1 shows the AVR Configuration System dialog box where devices can be
added or removed from the ICE unit.
Figure 3-1. AVR Configuration System Dialog
The left side column shows which devices are supported by the emulator, but not cur-
rently loaded. To be able to emulate one of these devices, the appropriate device should
be marked, and the “Add” button should be pressed.
Note: If 6 devices are already stored in the emulator, remove the appropriate number
of devices before trying to add more.
Once all wanted devices are listed in the right column press “Download” to start the
actual update of the ICE10. This might take a few minutes, and the green LED will flash
during the update. A dialog box will appear at the end of the update giving a confirma-
tion that the update was successful.
Note: The update will not take effect util the next time the emulator is turned on.
Using the ICE10
AVR® ATICE10 User Guide 3-3
3.5 Using Breakpoint ICE10 supports an unlimited number of breakpoints. Breakpoints can be placed directly
in the source code. When running the code, execution will be halted before executing
the code line with the breakpoint. ICE10 does not support advanced or complex break-
points. For in-depth description of breakpoints and how to use them, see the on-line
help system in AVR Studio.
3.6 Using Traces The ICE10 has a 32K x 96-bit trace buffer that stores information about program execu-
tion for every clock cycle. When the emulator is stopped, this trace buffer can be
examined to extract information about the history of the emulated program. The details
on which data are stored and how to retrieve them are described in the “AVR Studio On-
line Help.” When the trace buffer is full, it will wrap around and start overwriting the old-
est entries.
The trace buffer can be turned on or off at any program line. This makes it possible to
skip tracing delay loops and other subroutines which would otherwise fill the trace mem-
ory with unnecessary data. The trace buffer is inactive by default. To trace an entire
program, a Trace on marker should be placed on the first line of the program.
For in-depth description of Traces and how to understand the contents of the trace
buffer, see the on-line help system in AVR Studio.
3.7 Using Triggers The ICE10 has five external trigger inputs and five trigger outputs, all located on the Aux
connector next to the Pod connector. The pinout is shown in Figure 3-2 and Table 3-1.
The trigger inputs can act as break signals to the emulator and/or they can be logged
in the trace buffer. Any inputs set up to break the emulator are activated when a rising
edge is detected.
The trigger outputs may be set as trigger points on any instruction in the code window
in AVR Studio. If enabled on an instruction, the output(s) will remain high for one AVR
clock cycle when the marked instruction is executed. This can be used to trigger a
logic analyzer or an oscilloscope.
Figure 3-2. AUX Connector
Using the ICE10
3-4 AVR® ATICE10 User Guide
There are three global mask registers that are used to control the behavior of the
triggers:
The Trigger Output Global Mask Register controls which of the output pins are
allowed to be controlled by the trigger settings in the code. An output pin that is
disabled will remain low even if a trigger point for that particular pin is set in the code.
The Trigger Input Global Mask Register controls which of the input pins are allowed to
break the emulator. If more than one line is enabled, the emulator will break on either
one, but will not store any information about which input caused the event. Note that
unconnected inputs are pulled high by internal pull-up resistors. Unused lines must
not be enabled.
The External Trace Mask Register controls which of the input pins will be stored in the
trace memory. Input pins that are not enabled in this register will be stored as zero in
the trace memory. To be traced, input signals must be valid and stable at the rising
edge of the AVR clock and for 50 ns thereafter. It is also necessary that the trace
buffer is enabled.
The trigger input and the external trace are two independent functions acting on the
same input pins. Note that the trigger logic is asynchronous and edge driven, whereas
the trace logic is clocked on the AVR clock. The emulator may therefore break on a
glitch signal that is too narrow to be traced.
The details on how to enable and set up triggers and mask registers are presented in
“AVR Studio On-line Help”.

Figure 4-1. Component Placement of AT90ADCPOD
The AT90ADCPOD contains the following functions:
Analog comparator
Clock circuits for handling of the timer oscillator and XTAL signals from the target
application
Analog to digital converter
Bus switches for converting the voltage on the I/O signals
11 jumpers and one switch must be set on AT90ADCPOD to configure it for desired
operation.
4.2 Configuring the
AT90ADCPOD
AT90ADCPOD is connected to the ICE10 unit using the pod cable (the wide cable) and
to the user application using the 8-pin, 20-pin, 28-pin, or 40-pin probe.
Note: It is important that the probe cable is correctly connected to the user application.
Only one probe cable should be connected. The colored wire of the probe cable
indicates pin 1 of the AVR device.
Use the appropriate probe cable and connect the application to the connector labeled
with the correct part number. Please note that the ICE10 may be damaged if the probe
cable is connected to the wrong connector.
The 8-pin AVR devices have multiple options for using port pins PB3, PB4 and PB5.
Please refer to data sheets for detailed information. To select how PB3 and PB4 should
be used, the jumpers labeled PB3 and PB4 must be set correctly. Table 4-1 shows the
settings for these jumpers.
AT90ADCPOD Configuration
AVR® ATICE10 User Guide 4-3
Note: The jumper setting does not affect operation for other devices.
ATtiny11 and ATtiny12 also have the possibility to disconnect the external RESET pin
and use it as a general I/O pin (PB5). This is done by setting the jumper marked RST in
position OFF. Jumper RST must always be set in position ON for all other devices.
To use AT90S2333, AT90S4433, AT90S4434, or AT90S8535, the 10-lead cable on the
pod must be mounted. Table 4-2 shows how to connect this cable.
Note: Connection of the 10-lead cable does not affect operation for other devices.
4.3 The ICE10 Power
System
The ICE10 system has an internal power regulator that can deliver 15W at 5V. The
ICE10 itself uses about 10W, so if the user application is powered from the ICE10 sys-
tem, it cannot use more than 5W (i.e. 1A/5V). If this value is exceeded, the ICE10
system may be damaged or not work properly.
The power supply delivered with your ICE10 is dimensioned to meet the requirements of
the emulator. If another power supply is used, it should supply a voltage between 9 and
15 VDC, minimum 20W. The battery eliminator connector on the ICE10 system is a
standard type with 2.1 mm center tap. Center tap is negative.
4.3.1 The Target
Applications Power
Requirements
If the target application should be powered from the ICE10, the jumper named
“EXT.POWER” must be mounted and the jumpers labeled “PW2”, “PW1” and “PW0”
removed.
If the target application has its own power supply, the jumper named “EXT.POWER”
must be removed. The ADCPOD must also be set to convert voltages to the required
voltage level. Use Table 4-3 to find the settings on the jumpers named “PW2”, “PW1”
and “PW0”.

The internal clock can be adjusted between 400 kHz and 20 MHz. Any frequency within
this range can be selected, and will be produced with an accuracy better than 200 PPM
for most frequencies.
If an external clock source from the user application is used this can be in the range of
32.768 kHz to 10 MHz. To use an external clock source, select External Oscillator in the
Emulator Options menu in AVR Studio. It is important to tune the oscillator driver by
choosing the corresponding range in the Clock Range menu to make the clock system
work properly with an external crystal.
On the pod card, the XTAL pins are connected to the ICE10 by using the 2-wire cable.
Connect the cable from J103 to the 2-pin header nearest the used probe connector.
Table 4-4 shows where to connect the 2-wire for various devices.
Pin 1 on each connector is labeled with *.
Connector J101 must be left open if the clock source from the user application is a crys-
tal, If the clock source from the user application is an oscillator, a jumper must be
mounted on connector J101. Table 4-5 shows the settings for J101. The switch S101
must be in position OFF in both cases.

Long leads from your external crystal to the oscillator circuit on the pod may cause prob-
lems. It is possible to mount a crystal in the socket near J103. Do not use the 2-lead
cable if you choose this option. If the crystal frequency is above 1 MHz and this is
selected in the Clock Range menu in Emulator Options in AVR Studio, S101 should be
in position ON. S101 should be in position OFF under all other circumstances.
Please note that a crystal cannot be used when emulating AT90S2343 or ATtiny22.
4.4.1 The Timer Oscillator This section only applies to emulation of S4434 and S8535.
A 32.768 kHz crystal is mounted on the pod for use with the Timer oscillator. It is impos-
sible to emulate the Timer oscillator with a crystal in the target application due to the
long leads from the target application to the oscillator circuit. If an external oscillator out-
put is used as the clock source of the Timer oscillator, mount jumper J104, otherwise
leave it open.
4.5 The Analog
Comparator
The jumpers labeled S0 and S1, must be set correctly to make the analog comparator
work properly. Table 4-6 shows how to set these jumpers.
Note: The jumper settings does not affect devices without Analog Comparator.

5.2.1 Serial Number Every ICE10 unit has a unique serial number. If technical support is needed, this num-
ber should be provided with a detailed description of the problem. The serial allows
technical support to track what firmware the specific ICE10 contains.
5.2.2 Serial Port RS232 C The ICE unit is connected to an RS-232 port on the host PC with the supplied RS-232
cable. All serial communication is done at 19200 bps using no parity, 8 data bits and 1
stop bit (N81).

5.2.5 AVR Reset Button This button resets the application. See Section 5.4 for details on different AVR reset
options.
5.2.6 ICE Reset Button The ICE Reset button is hidden in the back panel for safety reasons. If the emulator
starts to behave unpredictably, use a thin tool to push this reset button. The green LED
will be turned off for a while and will be switched on again when the system is ready.
When the ICE10 reset button is pressed, the program memory is cleared, thus the
project file must be closed in AVR Studio and then reopened.
5.2.7 ON-OFF Switch On-Off switch for the Emulator. Do not turn off power on the emulator while there still is
power on the target board. This might damage the pod.
5.2.8 12V DC Connector The battery eliminator connector on the ICE10 system is a standard type with 2.1 mm
center tap. Ground should be connected to the center tap.
5.3 Power System The ICE10 system has an internal power regulator that delivers 15W at 5V. The ICE10
itself uses about 10W. The power supply delivered with the ICE10 is dimensioned to
meet the requirements of the emulator. If another power supply is used, it should supply
a voltage between 9 and 15VDC and a minimum of 20W. The battery eliminator connec-
tor on the ICE10 system is 1 standard type with 2.1 mm center tap. Ground should be
connected to the center tap.
Note: The target application power must not be present when the emulator is turned
off, as this may cause damage to the pod.
5.4 Reset System The ICE10 has two independent reset systems. One is for the ICE10 itself and the other
is for the emulated AVR device. The ICE10 reset button is placed on the back panel of
the box. The AVR reset system can reset the emulated device both when the device is
running and stopped. This reset can be activated from several sources:
The push-button marked AVR RESET on the back panel of the AVR ICE unit
(only when running)
The push-button marked RESET on the pod (only when running)
The reset button in AVR Studio. Note that the reset button in AVR Studio will stop the
emulation process if it is running when the button is pushed.
A reset signal from the user application (only when running)
Note: In order to enable external reset when emulating ATtiny15, the Enable External
Reset option must be selected in the AVR Studio Emulator Options dialog.
Please note that only a reset from the user application will reset other components in the
application connected to the AVR’s reset pin.
AVR® ATICE10 User Guide 6-1
Section 6
Special Considerations
There are a few important differences between emulating devices with the ICE10 and
running code in the actual device. In this section some of the special considerations are
listed. For more issues and considerations see the separate avrtools.pdf document on
the supplied CD-ROM, or download the latest version from the Atmel web site
(www.atmel.com).
6.1 Stack There is no hardware stack in the ICE10. Therefore, a stack must be set up in the emu-
lator’s SRAM when emulating devices with hardware stack. The following two
instructions will set up the stack.
ldi r16, $6F
out $3D, r16
Further writing to I/O locations $3D and $3E must be avoided.
6.2 Assembling Some instructions that are not available in tiny AVR devices will work in the ICE10. Use
the assembler device directive when assembling to generate warnings when illegal
instructions are used.
6.3 ADC The ADC featured in ATtiny15 is implemented on the ATtiny15POD using an AD con-
verter chip, several analog multiplexers, an operational amplifier to provide 20x gain and
an instrumentation amplifier to provide differential mode inputs. See Figure 6-1. Due to
this construction with discrete ICs on an open PCB, the ADC will be more susceptible to
ambient noise and have electrical characteristics that differ from the actual chip. See
Table 6-1.
Figure 6-1. ATtiny15POD
The internal voltage reference on the pod has a nominal voltage of 2.495V (minimum
2.440V, maximum 2.550V). This is within the specification of ATtiny15 (2.40V - 2.7V).

Special Considerations
6-2 AVR® ATICE10 User Guide
When measuring differential signals, the lowest possible signal is approximately 8 mV.
For any signals below this value, the voltage output of the instrumentation amplifier will
be 8 mV (maximum). When measuring single-ended signals, the instrumentation ampli-
fier is bypassed and the signal may be in the range 0V to VREF.
The differential amplifier and gain stages are supplied with 7V on the pod. To protect the
ADC chip from any voltage levels exceeding 5.8V (for instance, when using 20x amplifi-
cation and an input signal >0.29V), a clamping diode and a series resistor of 51Ω are
coupled to the ADC input pin.
Note: The signal applied to the ADC inputs multiplied with the selected gain (1x or
20x) should never exceed 5.5VDC.
The multiplexer selecting the reference voltage to the ADC has internal clamping diodes
to VCC on all inputs. If target VCC is present and the emulator power is switched off, the
clamping diodes will conduct current directly to GND. To limit this current, two 470Ω
resistors are coupled in series with external reference signal.
Under no circumstances should the target power be present while the emulator is
switched off.
IMPORTANT: In a critical application using ADC (for instance, a battery charger charg-
ing LiIon batteries), the emulator should not be used as a replacement for the actual
device during testing due to inaccuracy and noise in the ADC.
6.4 Noise Canceler
Mode
The ADC noise canceler mode featured is implemented as idle mode in ICE10, not
power-down mode as in the actual device.
6.5 Timer/Counter1 Due to synchronization of the CPU and Timer/Counter1, data written into
Timer/Counter1 is delayed by one CPU clock cycle. This applies to both the ATtiny15
device and ICE10 emulating ATtiny15. Due to this synchronization mechanism, values
written to TCNT1 in AVR Studio’s I/O view will not be updated before the program is
single stepped or another I/O location is written.
6.6 Analog
Comparator
The input voltage range of the analog comparator is 0 to 3.5 volts in ICE 10. Hence if
both inputs are > 3.5 volts, the output of the comparator is undertermined.
