um0139 emulation characteristics 21/38 watchdog 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 executab le 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 inte rrupt mapping to be configured as ei0 or ei1. 3.2 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. figure 15. hardware simulation window table 4. ext_it option bit mapping ei0 ei1 ext_it bit value pa[7:0] ports pb[7:0] ports pc[5:0] ports 1 pa[7:0] ports pc[5:0] ports pb[7:0] ports 0
emulation characteristics um0139 22/38 ta bl e 5 shows the hardware simulations that are available, depending on the target mcu that you have chosen in the mcu configuration window. 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 s. 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 s 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 s in the delay field. this simulation scenario allows you to si mulate 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 ta bl e 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 s in the delay field. in the hardware simulation window, choose the scenario you wish to simulate on the emulator, and enter the duration of t he interrupts (if applicable). click send to begin the simulation. table 5. hardware simulation functions by target mcu target mcu hardware simulations available st7226x lvd reset avd interrupt + lvd reset clock filter interrupt st7litex st7dali lvd reset avd interrupt + lvd reset

um0139 emulation characteristics 25/38 3.3.2 power follower characteristics the application power supply follower converts the application voltage v app 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 v cc_emu evolves with the value of v app . 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. caution: because the v ref used by the adc function is v cc_emu , and the v cc_emu value only coincides with the actual v app value when v app is between 2.5 to 5 v (refer to figure 16 ), the adc conversion will be erroneous when v app is outside of the 2.5 to 5 v range. figure 16. power follower behavior 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6 6.5 7 v app (v) 7 6.5 6 5.5 5 4.5 4 3.5 3 2.5 2 1.5 1 0.5 0 v cc_emu (v) v app (v) v cc_emu (v) v app (v) v cc_emu (v) 0 2.14 5.3 5.27 0.5 2.16 5.4 5.33 1 2.18 5.5 5.36 1.5 2.2 5.7 5.4 2 2.26 6 5.44 2.3 2.35 6.3 5.46 2.4 2.41 2.5 2.5 33 3.5 3.5 44 4.5 4.5 55 5.2 5.19
emulation characteristics um0139 26/38 3.4 emulation functional limitations and discrepancies some mcu?s may present specif ic 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 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 app ear. 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). 3.4.2 discrepancies when emulating the adc peripheral on all supported microcontrollers, a stabilization time of 20 s 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 s is needed to stabilize the adc system when setting this bit, ? 800 s is needed to stabilize the adc system when clearing this bit.

um0139 emc conformity and safety requirements 33/38 appendix a emc conformity and safety requirements this product respects the emc requirements of the european guideline 89/336/eec under the following conditions: any tester, equipment, or tool used at any production step, or for any manipulation of semiconductor devices, must have its shield connected to ground. all provided ferrites must be attached as described in the hardware installation instructions of the relevant user manual. the product must be placed on a conductive table top, made of steel or clean aluminum , or covered by an antistatic surface (superfic ial resistivity equal to or higher than 0.5 m ? /cm 2 ) , grounded through a ground cable (conductive cable from protected equipment to ground isolated with a 1 m ? resistor placed in series) . before every contact with the emulator, the operator must touch the surface of the grounded worktable just behind the rear panel of the emulator. all manipulation of finished goods must be done at such a grounded worktable. the worktable must be free of all non-antistatic plastic objects. an antistatic floor covering grounded through a conductive ground cable (with serial resistor between 0.9 and 1.5 m ? ) should be used. it is recommended that you wear an antistatic wrist or ankle strap, connected to the antistatic floor covering or to the grounded equipment. if no antistatic wrist or ankle strap is worn, before each manipulation of the powered-on tool, you must touch the surface of the grounde d worktable just behind the rear panel of the emulator. it is recommended that antistatic gloves or finger coats be worn. it is recommended that nylon clothing be avoided while performing any manipulation of parts.
changing the teb in your st7-emu3 probe um0139 34/38 appendix b 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. 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 static- free for future use.
um0139 changing the teb in your st7-emu3 probe 35/38 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 d eb connectors along the long edges of the teb. there is one 84-pin connector and o ne 64-pin connector, which match the deb connectors shown in figure 26 . figure 26. deb and teb connectors 5. 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. note: 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 microcontro ller. to compensate you will need to add a 10mm 5mm the 84 and 64-pin connectors on the deb teb 10mm teb support with 5mm extension
changing the teb in your st7-emu3 probe um0139 36/38 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 surfac e 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 u pdated automatically by stvd7 when you start a debug session. for more information refer to your stvd7 user manual .
