Introduction
The ST7-EMU3 series emulators are the third generation of high-end emulators for ST7.
EMU3 series emulators are designed to provide a complete range of advanced debugging
features during emulation. They come with all the adapters, connectors and sockets you
need to emulate any of the supported ST7 devices. In addition, they provide in-circuit
debugging and programming capability to give you start-to-finish control of application
development with ST7 Flash devices.
Your EMU3 probe is the component of the ST7-EMU3 emulator that contains targetemulation hardware. It connects to your PC via the ST Micro Connect box, and it can
connect to your application board in place of your ST7.
The EMU3 probe’s Target Emulation Board (TEB) contains the hardware that allows you to
emulate an ST7 or ST7 sub-family. The modularity provided by the TEB makes it possible to
emulate a range of ST7 MCUs with one ST7-EMU3 emulator. For this reason, the
ST7MDT10 target emulation board is delivered either as part of the ST7MDT10-EMU3
emulator kit, or independently, in the ST7MDT10-TEB kit.
The ST7MDT10-EMU3 emulator is designed to emulate MCUs in the ST7226x, ST7LITE
sub-families and the ST7DALI.

Note:
Solder the SO16 socket to your application board
Care must be taken when designing the circuitry
surrounding the component-side footprint for the
emulated SO16 device on your application board. This
is because the provided set of connection pins has
larger pins than the actual SO16 microcontroller
package.
If wire on wire connections are made on the SO16
(150-mil width) footprint between the two 8-pin rows
(as shown on the top-right), a short circuit may occur
when soldering the connection pins for the emulator on
the same footprint.
To avoid short circuits we recommend using wire on
wire connections as shown in the illustration on the
bottom-right.

This option allows you to choose whether the watchdog timer is enabled by software or by
hardware.
Refer to the datasheet of your target ST7 MCU for more information on the watchdog timer.
Watchdog halt
There are two options: Reset or No Reset. If this option is set to Reset, when the Watchdog
is enabled and a Halt instruction is encountered in the executable code, a chip reset will be
performed. If this option is set to No Reset, no chip reset will be performed.
EXT_IT
This option bit allows the Port C external interrupt mapping to be configured as ei0 or ei1.

Hardware simulation
The ST7MDT10-EMU3 emulator has a hardware simulation function that allows you to
simulate the reaction of the target MCU under certain circumstances. This feature can only
be accessed when your emulator is not running.
To access the hardware simulation function, select Debug Instrument > Hardware
Simulation from STVD7’s main menu bar.
Note:
The list of Simulation commands may vary according to the selected microcontroller.

AVD Interrupt + LVD Reset
The simulation scenarios that you may choose in the Hardware Simulation window are:
●
LVD (Low Voltage Detector) Reset: When this simulation is chosen, a chip reset is
generated immediately, as if low voltage had been detected by the emulator. The reset
generated typically lasts 30 µs.
●
AVD (Auxiliary Voltage Detector) Interrupt + LVD Reset: When this simulation is
chosen, an interrupt occurs immediately and lasts for a configurable duration. Once the
duration of the interrupt is over, a chip reset occurs (lasting 30 µs typically), and
immediately afterwards, another interrupt of the same configured duration occurs. To
configure the duration of the two interrupts, click on the downward arrow button, and
type in the duration in µs in the Delay field.
This simulation scenario allows you to simulate a power-down of the chip (first
interrupt), followed by a reset, and a power-up of the chip (2nd interrupt). By varying the
duration of the interrupts preceding and following the chip reset, you can simulate
different rates of powering down and up.
●
Clock Filter Interrupt: This feature is available with only certain target MCUs—see
Table 5. When this simulation is chosen, an interrupt occurs immediately, of
configurable duration. Once the interrupt is over, the program continues running. To
configure the duration of the interrupts, click on the downward arrow button, and type in
the duration in µs in the Delay field.
In the Hardware Simulation window, choose the scenario you wish to simulate on the
emulator, and enter the duration of the interrupts (if applicable). Click Send to begin the
simulation.

Emulation Characteristics
Power follower characteristics
The application power supply follower converts the application voltage VAPP to a voltage
within the range of 2.4 V and 5.5 V.
The curve plotted on the graph below shows how the value of VCC_EMU evolves with the
value of VAPP.
Note:
This curve this not necessarily characteristic of all emulators—it is based on measurements
taken using a single emulator. Slight differences may occur between emulators.

VAPP (V)
Because the VREF used by the ADC function is VCC_EMU, and the VCC_EMU value only
coincides with the actual VAPP value when VAPP is between 2.5 to 5 V (refer to Figure 16),
the ADC conversion will be erroneous when VAPP is outside of the 2.5 to 5 V range.

Emulation functional limitations and discrepancies
Some MCU’s may present specific limitations and discrepancies. You will find information
specific to your MCU and your hardware configuration in STVD7’s Discrepancies window.
For more information refer to the STVD7 User Manual
3.4.1
3.4.2
26/38
Limitations
●
The Flash status control register is not emulated; flash memory is replaced by ROM on
the emulator. Therefore, read/write access has been blocked at the FCSR address, to
avoid misinterpretation of the contents of this address. If you attempt a read/write
access the Flash Control/Status Register (FCSR), your program will stop running (the
equivalent of a breakpoint) and an “access denied” message will appear. If this occurs,
click Continue to continue running your program.
To avoid interruptions in the running of your program on the emulator, it is advisable to
temporarily comment out any read or write accesses to the FCSR.
●
For the ST7DALI and all targets in the ST7LITE2 family, the AMPCAL bit (bit 4) of the
AMP CONTROL/DATA REGISTER LOW (ADCDRL) register (part of the ADC
peripheral) can be set in STVD7 but will have no effect in emulation (this functionality is
not emulated).
Discrepancies
●
When emulating the ADC peripheral on all supported microcontrollers, a stabilization
time of 20 µs is required after changing the channel or starting a conversion.
●
For the ST7DALI and all targets in the ST7LITE2 family, stabilization time is required
when changing the Amplifier Control bit AMPON:
–
300 µs is needed to stabilize the ADC system when setting this bit,
–
800 µs is needed to stabilize the ADC system when clearing this bit.

In-circuit debugging connection with ICD adapter
In-circuit debugging connection with ICD adapter
This chapter describes the configuration and connection of the ICD adapter to your
application board for in-circuit debugging (ICD) of ST7FLITEUS and ST7FLITEU0
microcontrollers. Complete instructions for setting up your ST7-EMU3 series emulator for
ICD are found in the ST7-EMU3 Emulator User Manual.
Note:
The emulator comes with both ST7FLITEUS and ST7FLITEU0 devices in DIP16 package to
allow debugging of applications developed for either microcontroller. Ensure that the device
on the adapter corresponds to the target device for your application.
4.1
In-circuit debugging
ICD On jumper (TP1)
When in-circuit debugging the target application via the 10-pin ICC connection, the ICD On
jumper (TP1) must be fitted to allow the interface with an in-circuit debugging tool and the
host PC. During in-circuit debugging, the RST/PA3 On jumper (TP2) must not be fitted.
Figure 17. ICD On jumper (TP1)
MB509
TP2 not fitted
for ICD
TP1 fitted for ICD
To set the ICD On jumper (TP1):
1.
Make sure the in-circuit debugging tool and the application are powered off.
2.
Place the jumper on TP1 as shown in Figure 17.
3.
Connect to and power on the in-circuit debugging tool and application board.
Refer to the on-line help of your integrated development environment/debugging software
for further information about in-circuit programming and debugging the microcontroller on
the ICD adapter.
27/38
In-circuit debugging connection with ICD adapter
UM0139
CLKIN solder point (G2)
Your in-circuit debugging tool can provide the clock signal for initiating in-circuit
communication with the microcontroller on the ICD adapter. To do this, you must complete
the connection with a drop of solder on the CLKIN solder point (G2) shown in Figure 18.
Figure 18. CLKIN solder point (G2)
MB509
Solder point G2
When the solder drop is placed on the CLKIN solder point (G2), pin PA5 is relayed to CLKIN
on the ICC connector. PA5 is not available for the application.
When the clock signal is furnished by the in-circuit debugging tool, use the Option Bytes
Disabled mode to start the in-circuit debugging session. For further information about this
mode refer to the online help of your integrated development environment or debugging
software.
4.2
Run the application in standalone mode
Once the microcontroller on the ICD adapter has been programmed during an in-circuit
debugging or in-circuit programming session, it can run the application in place of the target
microcontroller without being connected to an in-circuit debugging tool or the host PC.
Figure 19. RST/PA3 On jumper (TP2)

Changing the TEB in your ST7-EMU3 probe
Appendix B
UM0139
Changing the TEB in your ST7-EMU3 probe
Each EMU3 probe has a modular design that is made up of three emulation boards. Two
boards, the Common Emulation Board (CEB) and the Dedicated Emulation Board (DEB)
are identical for all ST7-EMU3 probes. However, the third board, the Target Emulation Board
(TEB), is specific to an ST7 MCU, or a family of ST7 MCUs. Therefore, what makes each
EMU3 probe distinct and defines its emulation capabilities, is the type of TEB it contains.
The EMU3 probe has been designed to work with many different Target Emulation Boards
(TEBs). This appendix tells you how to replace the TEB in your EMU3 probe.
1.
Turn the EMU3 probe upside-down, unscrew the retaining screw and slide the bottom
out as shown in Figure 3 on page 7.
2.
Remove the two screws that secure the TEB to the rest of the probe boards, as shown
in Figure 24.
Figure 24. Removing the TEB screws
3.
34/38
Remove the target emulation board that is currently in the probe by gripping the edge of
the board and pulling it straight out (see Figure 25). Store it somewhere safe and staticfree for future use.
UM0139
Changing the TEB in your ST7-EMU3 probe
Figure 25. Removing the TEB
The board under the TEB – the Dedicated Emulation Board (DEB), should now be
visible (see Figure 26).
4.
Identify the top and bottom faces of the TEB you wish to install. The bottom face is
distinguished by the presence of two or more flex cable connectors placed side by side.
The top face is distinguishable by two DEB connectors along the long edges of the
TEB. There is one 84-pin connector and one 64-pin connector, which match the DEB
connectors shown in Figure 26.

5.
Note:
Install the replacement TEB in the EMU3 probe by inserting the male 84-pin/64-pin
connectors into the TEB’s female 84-pin/64-pin connectors (refer to Figure 26).
Because the connectors are asymmetric, there is only one possible connection
scheme.
For some TEBs, the microcontroller is mounted on a support and not soldered directly to the
board. In this case the TEB’s 84-pin and 64-pin connectors have an additional height of
5mm to allow enough room for the microcontroller. To compensate you will need to add a
35/38
Changing the TEB in your ST7-EMU3 probe
UM0139
5mm extension to the 10mm support on the DEB, as shown in Figure 26. The 5mm
extensions are provided with your TEB and screw into the 10mm supports. However,
remember that if you install a TEB with surface mounted microcontroller later, you will have
to remove the 5mm extensions.
6.
Once the TEB is firmly in place, refasten the two screws that fix the TEB to the DEB, as
shown in Figure 15. Take care not to over-tighten the screws.
7.
Connect the appropriate flex cable for your MCU package, as described in Section 2.1:
Connecting the flex adapter to the EMU3 probe on page 7.
8.
Replace the bottom panel of the probe housing such that the flex cable feeds through
the slot provided.
9.
Reconnect the probe to the ST Micro Connect box by connecting the two 80-pin flat
cables to the ST Micro Connect connection ports on the top face of the probe housing.
For details, refer to the ST7 EMU3 Emulator User Manual.
If this is the first time that you have installed a new TEB in your EMU3 probe, your emulator
and probe firmware will be updated automatically by STVD7 when you start a debug
session. For more information refer to your STVD7 User Manual.
