connected to a target device with an on-chip debug unit to efficiently debug hardware and software. 1.1 Features { USB connection The MINICUBE can be connected to the host machine via the USB interface (1.1/2.0). Since it operates on power supplied via USB, an external power supply is unnecessary. { On-chip debugging Debugging is possible with the target microcontroller mounted on the target system. Programs can be downloaded (programming) to the flash memory by using the flash self programming function of the microcontroller. { N-Wire interface, Nexus interface <R> Using a JTAG- and Nexus-compliant and Nexus interface, the QB-V850MINI can be used generally for V850E2M, V850E2, V850E1 and V850ES microcontrollers with the on-chip debug unit. The MINICUBE is a successor of the IE-V850E1-CD-NW (PCMCIA type), so that the debugging environment for the IE-V850E1-CD-NW can be ported as is to the QB-V850MINI. Note that the IE-V850E1-CD-NW cannot be used with V850E2M microcontrollers. { Inclusion of self-check board Using the self-check board that is supplied with the MINICUBE can perform self-testing for faults. The self-check board can also be used as the debug adapter for the V850ES/KJ1(+), V850ES/KG1(+), V850ES/KF1(+), and V850ES/KE1(+). 10 User's Manual R20UT0221EJ0301 CHAPTER 1 OVERVIEW 1.2 Before Using QB-V850MINI Be sure to confirm the package contents listed in this chapter before using the MINICUBE.

User's Manual R20UT0221EJ0301 25 CHAPTER 3 ON-CHIP DEBUGGING <R> 3.4 Designing Target System Circuits when Using V850E2M To debug the target system with the MINICUBE connected, a circuit to connect the MINICUBE is required on the target system. This section presents information required for circuit design. Read this information together with the information described in the user's manual of the target device. Note that circuit design information when the target device is the V850E2, V850E1, or V850ES is described in 3.5 Designing Target System Circuits When Using V850E2, V850E1, or V850ES. 3.4.1 Example of circuit design (for V850E2M only) Figure 3-5 illustrates an example of the design of a target system circuit that is used to connect the MINICUBE. To determine the resistance of the resistors in the circuit, see the user's manual of the target device. Figure 3-5.

(1) Keep the pattern length as short as possible. (2) If VDD is between 2.0 and 5.5 V, it is judged that target system power is being supplied, and the signals switch to being used as debug signals. If VDD is not between 2.0 and 5.5 V, it is judged that the system has not been configured correctly, regardless of whether target system power is being supplied or not. In this case, the DRST, DCK, DMS, DDI, FLMD0, and RESET pins become high impedance, regardless of the operating status of the debugger. To avoid this, be sure to input the voltage from the power supply pin on the target device directly to VDD. (3) The circuit for connecting FLMD0 varies when using flash self programming or using microcontrollers that do not have an on-chip flash memory. See 3.4.3 Connecting the FLMD0 signal (for V850E2M only) for details. (4) To reset the target device while the target system power supply is on, connect the RESET signal. See 3. 4. 4 Connecting RESET (for V850E2M only) for details. User's Manual R20UT0221EJ0301 27 CHAPTER 3 ON-CHIP DEBUGGING 3.4.3 Connecting the FLMD0 signal (for V850E2M only) FLMD0 is the signal used to switch the system to flash programming mode.

At this time, make sure that the RESET signal does not conflict with the RESET signal generated on the target system. When none of the following conditions are satisfied, leave open the pin for the RESET signal that is output from the MINICUBE. * The target device should be kept in the reset state before debugger startup or after debugger termination. * The OCD signal pins (DCK, DDI, DDO, DMS, and DRST) are alternate-function pins in the specifications of the target device, the OCD signal becomes inactive due to a reset by other than the RESET pin, and the OCD signals are not set to active in the startup routine. For example, when using a device in which the pins that alternately function as the OCD signal pins are controlled by the OCDM0 register as shown below, the OCDM0 register is cleared to 0 upon reset by POC, so the OCD signals are not specified and as a result, on-chip debugging cannot be performed normally.

SW1 Setting (Self-Check Board) SW1 Setting Adapter Mode Adapter mode Description A setting to set the mode for performing debugging with in-circuit method. This is the default setting of SW1. Self Check Self-check mode A setting to set the mode for performing self-testing. This setting is also used to set the mode for writing to the PD70F3318YGJ on the V850MINI self-check board using a flash memory programmer. This mode is used to erase the on-chip flash memory when the debugger cannot be activated because the user has skipped setting of the security ID code. User's Manual R20UT0221EJ0301 57 CHAPTER 4 DEBUGGING WITH IN-CIRCUIT METHOD 4.3.5 Mounting target connector Mount the target connector on the target system in the following order. (1) Apply cream solder to the foot pattern for mounting the IC on the target system. (2) The target connector has a cylindrical projection in the center of the underside (Figure 4-4). Apply a twocomponent hardening type epoxy adhesive agent (a type that hardens in 15 to 30 minutes) sparingly to the underside of the projection to temporarily secure the connector at the specified location on the target system. Make sure that the position of pin 1 of the connector (where the corner is cut) matches the position of pin 1 on the target board. Figure 4-4. Target Connector Projection Diagram (3) Mount the target connector under the following conditions. a. To mount the target connector by reflow: 245C within 20 seconds (heating) b. To mount the target connector by manual soldering: 320C within 5 seconds (per pin) Caution The flux splashing that takes place while the connector is being mounted often results in defective conduction. Be sure to cover the upper part of the connector with aluminum foil. Avoid flux cleaning since the connector has a structure in which flux solvent is likely to remain. 58 User's Manual R20UT0221EJ0301 CHAPTER 4 DEBUGGING WITH IN-CIRCUIT METHOD 4.3.6 Connection and startup of system Connect and start the system in the following order. (1) Connecting MINICUBE to target system Connect the MINICUBE to the target system using the exchange adapter and target connector.

Self Check 60 User's Manual R20UT0221EJ0301 CHAPTER 4 DEBUGGING WITH IN-CIRCUIT METHOD 4.5 Cautions on Using Sockets This section describes cautions on using sockets such as the target connector and exchange adapter. The following symbols are used in this section. * TC: Target connector * EA: Exchange adapter * MA: Mount adapter * CA: Check pin adapter * SA: Space adapter * EP: Extension probe 4.5.1 Cautions on inserting/removing sockets * When inserting an adapter such as EA, MA, or SA in TC, insert it so that the position of pin 1 (where the corner is cut) on each adapter matches. Be sure to insert the connectors in the correct direction (so that the positions match). * Remove or insert the sockets in the correct direction (see Figure 4-7). * Be sure to hold the lower (mating) connector or board with your fingers when inserting or removing a socket. * Use a bamboo spit or similar object as a tool to remove the connector. Insert the tool between TC and EA and remove TC in the correction direction as shown in Figure 4-7. If force is applied to the connector in the wrong direction, the connector will be damaged. If only a metallic object such as a screwdriver is available as leverage, wrap its tip in a soft cloth. Figure 4-7. How to Insert/Remove a Socket 4.5.2 Causes of faulty contact of connectors and countermeasures for them Possible causes of faulty connector contact and countermeasures are listed below. * If flux gets inside TC when it is mounted Thoroughly clean the flux with a solvent such as alcohol. Cleaning must be performed at least 5 to 6 times. If conduction is still not stable, repeat cleaning. * If dirt gets inside the connector If dirt, such as threads, gets inside the connector, defective conduction occurs. Remove any dirt with a brush. * Cautions on using CA, SA, and EP When CA, SA, or EP is inserted, a very small amount of delay in the signal propagation and capacitance occur. Thoroughly evaluate these points after CA, SA, or EP is connected to the target system. User's Manual R20UT0221EJ0301 61 CHAPTER 4 DEBUGGING WITH IN-CIRCUIT METHOD 4.6 Recovery of Security ID This section describes how to recover from the case where the software tool cannot be activated because the user forgot the ID code or has skipped setting of the ID code, when using the V850MINI self-check board. Perform the following steps to recover from the above cases. (1) Remove the V850MINI self-check board from the target system. (2) Set SW1 on the V850MINI self-check board to "Self Check". (3) Connect the flash memory programmer to the FW1 connector on the self-check board. Caution To avoid signal conflicts, do not connect the MINICUBE to the self-check board when the flash memory programmer is connected. Do not supply the clock from the flash memory programmer during writing/erasure. (Use OSC1 on the self-check board as a clock for writing.) (4) Enter the settings for the flash memory programmer. Figure 4-8 shows setting examples when using the PG-FPL as the flash memory programmer. (5) Perform a chip erase operation. After the chip erasure, the security ID is set to "0xFFFFFFFFFFFFFFFFFFFF".

User's Manual R20UT0221EJ0301 67 CHAPTER 6 CAUTIONS This chapter lists cautions on using the MINICUBE. Caution items are classified in the following three categories, so refer to the relevant items. [OCD] Cautions for performing on-chip debugging [IE] Cautions for performing debugging with in-circuit method [SC] Cautions for performing self-testing Table 6-1. List of Cautions (1/2) No. 1 Classification [OCD] Caution Use of target devices used for on-chip debugging as mass production products is not guaranteed. Guarantee for the case where only downloading of a program is performed but debugging is not performed is planned. 2 [OCD] In a target device that incorporates an OCD unit, some of the target interface signal pins for OCD may have alternate functions. The alternate functions of these pins cannot be used during on-chip debugging. 3 [OCD], [IE] When erasure and write are prohibited by setting the security flag for the flash memory, programs cannot be downloaded via the debugger. 4 [OCD], [IE] If DMA transfer to the internal RAM is performed while a program is being downloaded to the flash memory, downloading of the program may not be performed normally because the integrated debugger uses the internal RAM during program downloading. 5 [OCD], [IE] Do not use the ROM correction function or else unexpected breaks will occur. 6 [OCD] Since the initial value of the ASID register in the V850E1 Series is undefined, set the ASID register to 00H via the reset routine. Initialization of the V850ES Series is not required. 7 [OCD] The current consumption in the target device increases during debugging compared with that in normal operation mode, because the OCD unit of the target device operates during debugging. 8 [OCD] The break function may malfunctions when a reset occurs during RUN (program execution), depending on the target device. See the documents of the target device (user's manual, restriction notification, etc.). 9 [OCD] The I/O buffer (port pin) may enter the reset status depending on the target device when a reset is input from the pin, even if reset is masked by the mask function. See the documents of the target device (user's manual, restriction notification, etc.). 10 [OCD] No break occurs in an interrupt service routine for an interrupt acknowledged during self programming, even if an event breakpoint has been set. 11 [OCD], [IE] When using the self programming function, set the debugger so that the clock for the peripheral macros does not stop during breaks; otherwise, the flash memory may be damaged. 12 [OCD], [IE] When using the self programming function, do not set software breaks to the ROM area; otherwise, an unexpected break may occur. 13 [OCD] With the V850E1 Series, a forced break may be executed via the debugger operation during flash self writing. After a forced break, reexecute the program via the debugger or reset the CPU. 68 User's Manual R20UT0221EJ0301 CHAPTER 6 CAUTIONS Table 6-1.

Therefore, be sure to input the same voltage level to VDD and EVDD. 15 [IE] The P05, P52, P53, P54, and P55 pins are used for connecting the on-chip debug emulator, so these ports cannot be used. 16 [IE] The X1, X2, XT1, and XT2 pins are not connected to the target system. Consequently, the oscillation circuit in the target system cannot be used. 17 [IE] Do not apply a high voltage (5.5 V or higher) to the VPP pin; otherwise, the MINICUBE may be damaged. 18 [IE] The REGC pin is not connected to the target system. The REGC pin is connected to VDD inside the emulator. 19 [IE] The MINICUBE and the flash memory programmer cannot be connected at the same time. 20 [IE] The MINICUBE outputs a high-level signal to the FLMD0 pin while a program is being downloaded. (The MINICUBE output becomes the high-impedance state when no program is being downloaded.) Note the FLMD0 pin connection on the target system side. 21 [IE] When the flash memory programmer is connected, no clock can be supplied from the programmer. Use a clock on the self-check board (8 MHz at shipment) for writing or erasing data from the flash memory programmer. 22 [IE] Note the following points concerning the settings in the Configuration screen when the debugger is activated. * "Chip" area Select the device to be used. * "Clock" area Set as follows. - Main OSC: Input a frequency of the resonator mounted in OSC1 with the socket (Input "8" when using OSC1 with the default setting). - Multiply rate: Input the maximum multiplication rate of the frequency used for the resonator mounted in OSC1 with the socket. - Sub OSC: Input "32.768". * "ID Code" area Input the security code that has been set at addresses 0x70 to 0x79. At shipment, the debugger can be activated by inputting "FFFFFFFFFFFFFFFFFFFF". * "N-Wire I/F" area Be sure to select "DCK=10MHz". The debugger may not operate if "DCK=20MHz" is selected. Figure 6-1 shows the screen image for the above settings. 23 [IE] The P00 pin outputs a low-level signal during a reset. Exercise care when performing emulation of the V850ES/KE1, V850ES/KF1, V850ES/KG1, or V850ES/KJ1. 24 [SC] Do not connect the target system when performing self-testing.
