(4) Using the clock generated from a 6.876 to 8 MHz oscillator on the QB-V850EIA4. (5) Using the clock generated from a 4.0 to 6.875 MHz oscillator on the QB-V850EIA4. Cautions 1. In this product, clock input from the target system is not supported. 2. Clock when emulating the V850ES/IK1 During emulating the V850ES/IK1, half the clock mounted on the MAIN CLOCK is used as the clock in the QB-V850EIA4. Therefore, to the MAIN CLOCK, mount a resonator or oscillator whose frequency is twice that of the clock that is mounted to the target system. To use a 4 MHz clock as the main clock, for example, mount an 8 MHz clock (= two times as 4 MHz) on the MAIN CLOCK. 20 User's Manual U17167EJ4V0UM CHAPTER 2 SETUP PROCEDURE 2.3.2 Clock setting methods This section shows the hardware settings when setting the clock.

Make connections with both the QB-V850EIA4 and target system powered OFF. The following abbreviations are used in this section. * TC: Target connector * EA: Exchange adapter * MA: Mount adapter * CA: Check pin adapter * SA: Space adapter 2.6.1 Mounting target connector (TC) to target system (1) Apply cream solder to the foot pattern of the target system for mounting an IC. (2) A circular projection is at the center of the bottom side of TC (refer to Figure 2-7). Sparingly apply two-liquid hardening epoxy adhesive (type that hardens in 15 to 30 minutes is recommended) to temporarily secure the connector at the specified position on the target system. At this time, match the position of pin 1 (position where a corner of the connector is cut into shape C) with the position of pin 1 from the target system. (3) Soldering condition of TC (a) Reflow soldering At 245C for a maximum of 20 seconds (main heating) (b) Manual soldering At 320C for a maximum of 5 seconds (per pin) (4) Precautions on flux splatter If the solder flux splatters when the connector is soldered, faulty contact may occur. Be sure to cover the upper part of the connector with aluminum foil. Do not clean the connector because the flux solvent may remain inside the connector. 2.6.2 Plugging exchange adapter (EA) into TC Figure 2-7. TC Projection Match the No. 1 pin position of the EA, MA, CA, or SA to the No. 1 pin position of the TC and plug in (C cuts match in both). (a) When plugging or unplugging, hold down the TC with your fingers so that there is no force on the TC. (b) When plugging or unplugging, be careful of the direction of rocking (refer to Figure 2-8). As a tool when unplugging, insert some kind of thin non-conductive material such as a wooden stick in between the TC and EA and rock in the direction shown in Figure 2-8 while slowly unplugging. Be careful since the connector will be damaged if this is done in the wrong direction. Figure 2-8. Plugging and Unplugging User's Manual U17167EJ4V0UM 25 CHAPTER 2 SETUP PROCEDURE 2.6.3 Notes on handling TC, EA, MA, CA, or SA (1) Cause of faulty contact of connector (a) If flux gets inside the connector when TC is soldered It is easy for flux to get inside of the connector. Clean the connector several times with a solvent such as alcohol if flux gets inside. If conduction is still unstable, repeat cleaning. (b) If dust gets inside the connector Faulty contact occurs if dust such as a thread gets inside the connector. Remove dust with a brush. (c) Notes on using CA or SA When CA or SA is used, a fractional delay time of signal propagation and a little capacitance are generated as a result of inserting the adapter. Make a thorough evaluation by connecting the target system. (2) Notes on inserting and removing the connector (a) When inserting or removing the connector, be sure to hold down the lower (mating) connector or board with your fingers. (b) Before inserting a connector, make sure that the connectors are correctly positioned. If the connector is inserted incorrectly positioned, it may be damaged. (c) When removing a connector, insert some kind of thin non-conductive material such as a wooden stick beneath the connector to protect the board from being damaged. Do not remove the connector all at once. Remove the connector by jiggling it bit by bit. If only a metallic object such as a screwdriver is available, wind a soft cloth around its tip. 2.7 Mounting and Connecting Connectors (When Using T Type) This section describes the methods for connecting the QB-V850EIA4 to the target system when using the T Type. Make connections with both the QB-V850EIA4 and target system powered off. The following abbreviations are used in this section. * TC: Target connector * YQ: YQ connector * EA: Exchange adapter * MA: Mount adapter * CA: Check pin adapter * SA: Space adapter 2.7.1 Mounting TC in target system (1) Thinly apply a two-component epoxy adhesive (hardening time at least 30 minutes) to the ends of the four projections on the base of the TC and adhere the TC to the user board (clean the surface of the user board using alcohol or the like). If alignment of user board pads to TC leads is difficult, align them as in (2). (2) Align by inserting the guide pins for alignment for the TC (NQGUIDE) through the pin holes on the top of the TC. Accessory holes are 1.0 mm non-through holes in two or three places. (For hole positions, see the particular TC drawing.) 26 User's Manual U17167EJ4V0UM CHAPTER 2 SETUP PROCEDURE (3) Solder after fitting the MA to the TC. This is to prevent troubles such as flux or solder splatter and adhering to the TC contact pins when soldering. Soldering conditions Solder reflow Manual soldering Caution At 260C for a maximum of 10 seconds At 350C for a maximum of 5 seconds (per pin) Do not perform cleaning by flux immersion or vapor. (4) Remove the guide pins. 2.7.2 Connecting YQ on TC (1) After confirming that there are no broken or bent YQ contact pins, fit the YQ in the TC and fasten it using the supplied YQGUIDE (for the fastening method, see the next step, (2)). If repeatedly inserting and removing, be sure to inspect the YQ pins before fitting. If pins are bent, correct them using something thin and flat such as the edge of a knife. (2) Fasten YQ to the TC on the target system using the supplied YQGUIDE. Fasten the screws equally in the four corners using the supplied flat-blade screwdriver or a torque driver. YQGUIDE is 0.054 Nm (MAX.). Too great tightening causes bad connections. Four screws for fitting to the MA (M2 x 10 mm / 4 units) are included with YQ. The tightening torque of EA YQGUIDE supplied with YQ YQ TC Target system 2.7.3 Inserting EA into YQ Match the pin 1 position of the YQ or SA (corner cuts match in both) to the pin 1 position of the EA and insert it. * When inserting or removing, press on the TC, YQ, and SA with a finger so that there is no force on the TC. * When inserting or removing, be careful of the direction of wiggling. As a tool when removing, insert some kind of thin non-conductive material such as a wooden stick between the YQ (SA) and EA and wiggle it while slowly removing. Be careful since the connector will be damaged if this is done in the wrong direction. User's Manual U17167EJ4V0UM 27 CHAPTER 2 SETUP PROCEDURE 2.7.4 Precautions for handling TC, YQ, and SA (1) When taking the TC from the box, press down on the body and take out the sponge first. (2) Since the pins of the YQ are thin and easily bent, be careful. When inserting it in the TC, confirm that there are no bent pins. (3) When screwing a YQ soldered to a board to the TC, fasten the screws in four places in turn using a #0 or #1 Phillips precision screwdriver or torque driver after tentatively tightening them. Fix the torque at 0.054 Nm (MAX.). If just one place is overtightened, it may cause poor contact. Moreover, a board being connected to the YQ must have accessory holes in prescribed positions (4 places: 2.3 mm or 3.3 mm). The 3.8 mm or 4.3 mm that is the screw head size is an area where wiring is prohibited. (4) In YQ and SA removal, since there is a danger of YQ pins being bent or broken when prying and wiggling, remove them gradually using a flatbladed screwdriver from four directions. Moreover, to connect and use the YQ and SA, screw the YQ to the TC according to the YQGUIDE (included with the YQ) using a 2.3 mm flatbladed screwdriver and then connect it to the SA. Fix the torque at 0.054 Nm (MAX.). If even one place is overtightened, it may cause poor contact.. (5) For the TC, YQ, and SA, since there is a danger that cleaning fluid on the structure will remain in the connector, do not perform cleaning. (6) TC, IC, and YQ cannot be used in combination. (7) An TC/YQ system cannot be used in an environment of vibrations or shocks. (8) It is assumed that this product will be used in system development and evaluation. Moreover, when used in Japan, Electrical Appliance and Material Control Law and electromagnetic disturbance countermeasures have not been applied. (9) Since there are rare cases of shape change if the box is left for a long time in a place where it is 50C or higher, for safekeeping, store it in a place where it is no higher than 40C and direct sunlight does not hit it. (10) For details about handling the TC, YQ, and SA, see the NQPACK series technical materials at the website of Tokyo Eletech Corporation. Tokyo Eletech Corporation website: http://www.tetc.co.jp/ (11) The check pin adapter QB-144-CA-01 is an optional product for IECUBE, and can be used to measure the waveform between IECUBE and the target system. Since the pins on the QB-144-CA-01 do not correspond to the pin layout in each device, the pin header cover must be mounted according to the device to be used. For mounting methods of the pin header cover, refer to [Related Information] on the following webpage. URL: http://www.necel.com/micro/english/iecube/index.html 2.7.5 Precautions for mounting IC using TC and MA (1) Confirm that there is no weld flash in the resin (sealant part) of the IC. If there is weld flash, remove it using a knife or the like. (2) Confirm that there is no weld flash breaking or bending of IC leads. In particular, confirm the planarity of IC leads. If there is abnormality in the planarity, correct that portion. (3) Viewing the TC contact pins from the top, if there are foreign bodies on them, remove them using a brush or the like. After confirming (1) to (3), fit the IC to the TC. Also fit the MA. (4) Put the supplied M2 x 6 mm screws in the four accessory holes of the MA and fasten the screws in opposite corners. At that time, use either the dedicated screwdriver that is supplied or a torque driver to fasten them equally in turn with a tightening torque of 0.054 Nm (MAX.). Since the contact is poor if tightening is too great, once you have lightly fastened the MA screws, tighten them again. 28 User's Manual U17167EJ4V0UM CHAPTER 2 SETUP PROCEDURE (5) Depending on the use environment, when starting up a device that has been left for a long time, starting it may be difficult. In this case, loosen the screws slightly and then retighten them. (6) If startup still is difficult after (5) above, check (1) to (3) again. (7) Tightening the screws of the MA too much may give rise to cracks in the molded part of the MA (plastic part) and bend the mold into a bowed shape, making contact poor. (8) After soldering the TC, do not perform cleaning by flux immersion or vapor. 2.8 2.8.1 Connecting QB-V850EIA4 to Target System When not using extension probe (QB-144-EP-01S/02S) The QB-V850EIA4 can be connected to the target system without using an extension probe. Adjust the height by using the spacer at the rear part of the QB-V850EIA4, so that no stress is applied to the exchange adapter, the target connector, and other connectors. Sufficiently insulate the target system. Figure 2-9. Connection Without Extension Probe QB-V850EIA4 Height adjustable Exchange adapter Rear spacer Target connector User's Manual U17167EJ4V0UM 29 CHAPTER 2 SETUP PROCEDURE 2.8.2 When using extension probe (QB-144-EP-01S/02S) When using the extension probe (QB-144-EP-01S/02S), connect the QB-V850EIA4 and the target system in the following procedure. (a) Connecting probe holder Use the probe holder (supplied with the QB-V850EIA4) to connect the extension probe to the QB-V850EIA4, as shown below. Figure 2-10. Using Probe Holder <1> Connect the QB-V850EIA4 and probe. Extension probe Probe holder Insert <2> Insert the probe holder into QB-V850EIA4. QB-V850EIA4 Insert the probe holder into QB-V850EIA4 until you hear a click (note the direction). (b) Connection of extension probe GND wire There are 3 GND wires in the extension probe. Connect them to the QB-V850EIA4 and target system. <1> Fasten the GND wire on the QB-V850EIA4 side of the extension probe to the nut on the bottom of the QB-V850EIA4 using a #0 or #1 Phillips precision driver (connection of (B) to (A) in Figure 2-11). <2> Next plug the connector on top of the extension probe into the connector at the opening on the bottom of the QB-V850EIA4 from below being careful of the insertion direction (connection of (C) in Figure 2-11 to QB-V850EIA4). 30 User's Manual U17167EJ4V0UM CHAPTER 2 SETUP PROCEDURE Figure 2-11. GND Wire QB-V850EIA4 Target system <3> Connect the exchange adapter and extension probe to the target connector. <4> Connect two GND wires on the target system side of the extension probe to the target system GND. If a pin or screw is fastened to the target system GND, remove the transparent terminal cover on the end of the GND wire and fasten the Y type pin of the GND wire to the target system ((G) in Figure 2-11). If the GND on the target system is an exposed pad, likewise fasten the Y type pin to the pad on the target system by soldering ((H) in Figure 2-11) (recommended soldering iron temperature setting: 300C). <5> If the target system has only one GND, connect only one of the GND wires of the extension probe. Cut off the other GND wires with a nipper or leave it as is without removing the pin cover. User's Manual U17167EJ4V0UM 31 CHAPTER 2 SETUP PROCEDURE <6> Since the length of the GND wire below the head (insulated part) is approximately 60 mm, there must be at least a GND to which it can be connected to within the range of the three approximately 60 mm radius sections of the target system for connecting the extension probe, as shown in Figure 2-12. The GND wire of the extension probe is soldered to positions J and K in Figure 2-12. To connect it to position L, remove the wire soldered to J or K and then solder it to L. Figure 2-12. Where GND Wire Can Be Connected Target system 32 User's Manual U17167EJ4V0UM CHAPTER 2 SETUP PROCEDURE (c) Ensuring isolation When connecting the target system to the QB-V850EIA4 using an extension probe, adjust the height using the front spacer or rear spacer of the QB-V850EIA4 and ensure isolation from the target system. Figure 2-13. Connection Using Extension Probe QB-V850EIA4 Extension probe Exchange adapter Rear spacer (Height adjustable) Target connector Front spacer (Height adjustable) (d) Cautions related to extension probe The following cautions pertain to using the extension probe. <1> Be careful that stress of the extension probe is not placed on the target connector. Moreover, when removing the extension probe, remove it slowly while holding down on the exchange adapter with a finger so that there is no stress on the target connector. <2> Be sure to connect the GND wire of the extension probe to the QB-V850EIA4 and the target system. If not, the impedance of the cable becomes unstable, resulting in the lowering of signal transmission characteristics or distortion of the output waveform for an input waveform. User's Manual U17167EJ4V0UM 33 CHAPTER 2 SETUP PROCEDURE 2.9 Connecting USB Interface Cable and AC Adapter Plug the USB interface cable supplied with the QB-V850EIA4 into the USB connector of the host machine, and plug the other side into the USB connector on the rear of the QB-V850EIA4. Plug the AC adapter supplied with the QB-V850EIA4 into a receptacle and plug the other side into the power supply connector on the rear of the QB-V850EIA4. For QB-V850EIA4 connector positions, see Figure 2-14. By replacing the AC plug, the AC adapter can support the voltage from 100 to 240 V. The AC plug for 100 V is attached when shipped. Replace it with the AC plug for 220 or 240 V (supplied with the QB-V850EIA4) when the AC adapter is used at 220 or 240 V. Figure 2-14.

Power switch User's Manual U17167EJ4V0UM 35 CHAPTER 4 NOTES 4.1 Cautions Regarding Differences Between Actual Device And Emulator When debugging is performed with QB-V850EIA4 connected to the target system, QB-V850EIA4 performs emulation as if the actual device operates in the target system, although operations of the actual device and QBV850EIA4 differ in the following points. Therefore, the user is responsible for using the actual device for the final evaluation before starting mass production and judging its applicability. 4.1.1 Operation after power application to target system The target device mounted in the target system starts program execution when reset is released after power application. With QB-V850EIA4, however, the program will not be executed until manipulation to start the program downloaded with the debugger is performed. QB-V850EIA4 can download and execute objects even before their initial value information of a variable is ROMized, but the actual device does not operate normally if the objects have not been ROMized. For details on ROMization, refer to CA850 Ver.3.00 Operation User's Manual (U17293E). 4.1.2 Oscillator QB-V850EIA4 does not support clock input from the oscillator in the target system. The operating cock frequency may therefore vary between when the target device is mounted and when QB-V850EIA4 is connected. 4.1.3 Pin characteristics Since the connectors, adapters and circuit board are placed between QB-V850EIA4 and the target system, unlike when the target device is mounted in the target system, the electrical characteristics of the pins differ. In particular, note that the A/D converter conversion results can easily be affected. 4.1.4 Notes on flash self programming function The flash self programming function cannot be emulated. To use this function, make an evaluation by using an onchip debug emulator or the target device. Some devices support the pseudo emulation function, using a debugger. For the usage, refer to ID850QB Ver. 3.40 Operation User's Manual (U18604E). 4.1.5 Notes on DBTRAP instruction The DBTRAP instruction cannot be used in the user program because it is used for software breaks. 4.1.6 CLKOUT pin in standby mode The CLKOUT pin outputs the Low level in IDLE and STOP modes. The status before entering the IDLE or STOP mode is held in the actual device. 4.1.7 On-chip debug function Emulation of the on-chip debug function is not possible. 4.1.8 Current consumption The current consumed by QB-V850EIA4 differs from that of the actual device. The current consumption of QB-V850EIA4 is equal to or lower than that of the actual device during normal operation, and HALT and IDLE modes, but it becomes higher than that in the actual device in the STOP mode. 36 User's Manual U17167EJ4V0UM CHAPTER 4 NOTES 4.2 4.2.1 Notes On Debugging Notes on Non-map Break Figure 4-1. Break at Fetching Unused Area If a program is fetched from an area not used by a program (unused area) with an emulator, a non-map break usually occurs. However, a non-map break does not occur in the first 16-byte space of each unused area (refer to Figure 4-1). 4.2.2 PSC Register Access Used area (Non-map break does not occur) Non-map break does not occur in this area Unused area (Non-map break occurs) 16 bytes Used area (Non-map break does not occur) Unused area (Non-map break occurs) 16 bytes Used area (Non-map break does not occur) Data is written to the PSC register in the following sequence. If a software break is set to the NOP instruction immediately after the register has been accessed, the debugger hangs up. Example: mov 0x2,r1 st.b r1,prcmd st.b r1,psc nop nop Debugger hangs up if a software break is set here. There is no problem if a software break is set here or later. To set a break immediately after the PSC register has been written, use a hardware break. 4.2.3 Notes on DBPC, DBPSW, and ECR Registers The DBPC, DBPSW, and ECR registers cannot be accessed during a break. If a value is written to any of these registers during a break, the written value is ignored. If these registers are read, 0 is always read. 4.2.4 Notes on Trace Display Sequence When the trace mode that displays the access history is used, the display sequence may be reversed. * If read and write instructions are successively executed * If a bit manipulation instruction that executes read-modify-write is executed (such as SET, NOT, or CLR) In both the cases, the trace results of write and read are displayed in that order. 4.2.5 Notes on Starting Debugger When the debugger is started, the following warning or error may occur depending on the setting of the debugger and the status of the target system. This is because the status of the target system is not in accordance with the setting of the debugger. If a warning or error occurs, check the status of the target system or the setting of the debugger. It is recommended that the conversion adapter be connected to the QB-V850EIA4 even when the target system is not connected. If the conversion adapter is not connected, the value of the input port may not be correctly read.

To prevent these phenomena, set a software break. The conditions under which two instructions are simultaneously executed are shown on the following pages. 38 User's Manual U17167EJ4V0UM CHAPTER 4 NOTES [Combination of instructions for the occurrence of the simultaneous execution of two instructions] * Condition where "mov + operation instruction" are executed as one instruction If dst of mov and dst of the operation instruction are the same register, except r0, in combination of "mov src, dst" and one of the following instructions: Format I satsubr/satsub/satadd/mulh or/xor/and subr/sub/add Format II Remark shr/sar/shl/mulh "mov + operation instruction" are executed as one instruction only when the mov instruction is the first instruction of the above combinations of instructions. * Condition of parallel execution of instructions <1> Combination of one of the following instructions and br instruction Format I nop/mov/not/sld satsubr/satsub/satadd/mulh or/xor/and/tst subr/sub/add/cmp Format II Format IV mov/satadd/add/cmp shr/sar/shl/mulh sld.b/sst.b/sld.h/sst.h/sld.w/sst.w <2> Combination of one of the following instructions (instructions that do not update flags) and bcc instruction except br instruction Format I Format II Format IV nop/mov/sld mulh/sxb/sxh/zxb/zxh mov/mulh sld.b/sst.b/sld.h/sst.h/sld.w/sst.w <3> Combination of one of the following instructions and sld instruction Format I nop/mov/not satsubr/satsub/satadd/mulh or/xor/and/tst subr/sub/add/cmp Format II mov/satadd/add/cmp shr/sar/shl/mulh Remark Of <1> to <3>, two instructions are simultaneously executed only when the second instruction of the above combinations of instructions is br/brcc/sld Caution Formats I, II, and IV are the instruction formats described in the V850E1 Architecture User's Manual (U14559E). User's Manual U17167EJ4V0UM 39 CHAPTER 4 NOTES * Cases in which two instructions are not simultaneously executed In the following cases, two instructions are not simultaneously executed. (a) If the first instruction is the first instruction after execution branches to an address that is not word aligned. Example 0x1006 0x1008 mov r10,r12 sld.b 0x8[ep],r11 If a branch to address 0x1006 occurs, the two instructions are not executed simultaneously because the first instruction is not word aligned (because the lower 1 byte of the address is not 0, 4, 8, A, or C). (b) If the second instruction is sld and writing to the ep register is not completed. Example 0x1004 0x1006 mov r10,ep sld.b 0x8[ep],r11 In this case, the value of r10 is written to the ep register by the mov instruction at address 0x1004. However, the two instructions are not executed simultaneously because WB (writeback) of the mov instruction is not completed when the sld.b instruction at address 0x1006 is executed. (c) If the second instruction is bcc (conditional branch instruction) and a flag hazard occurs (the instruction immediately before or the instruction before that instruction may update the flags). Example 0x1004 0x1006 cmp r0,r10 bn 0xf0 The bn instruction that references the S flag and branches must wait for execution of the cmp instruction at address 0x1004 because the S flag is changed by the cmp instruction. As a consequence, the bn instruction causes a flag hazard and the two instructions are not executed simultaneously. (d) If the second instruction is sld and both of the load buffers are in the WB wait status. Example Suppose that the following instructions are located in the memory. 0x1000 0x1002 nop nop 0x1004 ld.w 0x3000[r10],r11 0x1008 ld.w 0x3004[r10],r12 0x100c mov r8,r9 0x100e sld.b 0x10[ep],r13 If ld.w at addresses 0x1004 and 0x1008 accesses the external memory, several clocks of wait states are inserted. If the instruction at address 0x100e is executed, then the load buffer is in the "WB wait" status because WB of the ld.w instructions at addresses 0x1004 and 0x1008 is not completed, and the two instructions at address 0x100c and 0x100e are not simultaneously executed. 4.2.7 Operation during Break Since various peripheral functions operate even during breaks in the in-circuit emulator, interrupts due to peripheral functions, generated during breaks, are suspended and, when re-executing after the breaks, execution may occur after processing of suspended interrupts. The watchdog timer counter, however, stops during the breaks. The following peripheral functions can be stopped when using the peripheral break functions. When using the ID850QB, this setting can be made in the Configuration dialog box. 40 User's Manual U17167EJ4V0UM CHAPTER 4 NOTES * Timer P * Timer Q * Timer M * Watch timer 4.2.8 RAM. A non-map break occurs if all of the following conditions are satisfied, even if the program itself is correct. * A program is executed in the internal RAM area. * Data access for the internal RAM area is performed twice in succession. * An execution branches to the internal ROM area using a JR or JARL instruction immediately after the above successive data access, or one NOP instruction after the above successive data access. In order not to generate the break, cancel the fail-safe break setting for the internal RAM in the debugger. An illegal break may occur when a peripheral I/O register is accessed during program execution in the internal When motors are controlled with timer pins, the motor control signal is not fed back upon CPU stoppage (break), which may have an adverse effect on the motor. To avoid this, QB-V850EIA4 supports the open break function that is used to set timer pins to the high impedance state upon CPU stoppage. The following pins are subject to the open break function. For details on the open break function settings, refer to ID850QB Ver. 3.40 Operation User's Manual (U18604E). Target pin : TOQ0T1-TOQ0T3, TOQ0B1-TOQ0B3, TOP21, TOQ1T1-TOQ1T3, TOQ1B1-TOQ1B3, TOP31 4.2.10 Conflict between program execution for internal RAM and DMA transfer If the following two operations are executed at the same time, the CPU may deadlock due to an internal bus conflict. * Instruction for accessing data at addresses mis-aligned in the internal RAM * DMA transfer for the internal RAM User's Manual U17167EJ4V0UM 41 CHAPTER 5 OPTIONAL FUNCTIONS The following functions can be added to the QB-V850EIA4.
