1 chapter 1 general chapter 1 general this chapter describes the outline of the EP-78024. 1.1 operating environment the EP-78024 is a probe set that connects an in-circuit emulator and a target system. by connecting the in- circuit emulator and target system with the EP-78024, the debugging environment of a microcontroller is established and the hardware and software of the target system can be debugged. for details of connection, refer to chapter 2 connection . figure 1-1. operating environment ? connecting in-circuit emulator and target system { in-circuit emulator target system emulation probe connector board emulation board EP-78024
2 chapter 1 general 1.2 organization the EP-78024 consists of an emulation probe and a connector board. (1) emulation probe the emulation probe consists of the following three parts: n n probe connects the in-circuit emulator and target system. ? EP-78024cw-r : 64-pin cw probe ? EP-78024gf-r : 64-pin gf probe n n ground clip connected to gnd of the target system to make the gnd potential of the in-circuit emulator the same as that of the target system and thereby improve the resistance to static electricity and the noise immunity of the system. n n external sense clip consists of eight sense clips which are used to check the voltage level of the pins of the ic mounted on the target system. (2) connector board the connector board connects the pins on the emulation board which output signals to the emulation probe, and is connected to the connector note on the emulation board. note the location on the emulation board at which the connector board is to be connected differs depending on the emulation board. refer to the users manuals of the in-circuit emulator or emulation board.

5 chapter 2 connection chapter 2 connection this chapter describes how to connect the EP-78024, turn on/off the power, and remove the emulation probe from the target system. 2.1 connecting in-circuit emulator and target system connect the in-circuit emulator and target system following these steps: (1) connect the emulation board and connector board. note that the board to be connected differs depending on the in-circuit emulator used. (2) connect the in-circuit emulator and emulation probe. (3) connect the emulation probe and target system. (4) connect the external sense clip (when the external sense clip is used). (5) turn on the power. each step, (1) to (5), is described in detail next.
6 chapter 2 connection (1) connecting emulation board and connector board <1> turn off the power to the in-circuit emulator. <2> connect the emulation board and connector board. <3> install the emulation board (with the connector board connected) to the in-circuit emulator. caution if the connector board is inserted to a wrong connector on the emulation board, the in-circuit emulator may be damaged. in the following description, it is assumed that the emulation board ie-78044-r-em is used. <1> turn off the power to the ie-78000-r. <2> connect cn3 and cn4 of the connector board to cn3 and cn4 of the ie-78044-r-em. <3> remove the screws (at six places) from the top of the ie-78000-r, and open the lid. <4> pull the card pullers at both edges of the ie-78000-r-bk in the in-circuit emulator toward you to pull out the board. <5> secure the ie-78044-r-em and ie-78000-r-bk with screws. <6> return the ie-78000-r-bk, onto which the ie-78044-r-em has been mounted, to the original position in the ie-78000-r. figure 2-1. connecting ie-78044-r-em and connector board h connector board emulation board (ie-78044-r-em) cn3 cn3 cn4 cn4 remark the shape of the emulation board differs depending on the model, but connection between the emulation board and connector board is the same as shown in figure 2-1. for details of how to mount the board to the in-circuit emulator, refer to the users manual of the in-circuit emulator.
7 chapter 2 connection (2) connecting in-circuit emulator and emulation probe <1> connect the emulation probe to the emulation probe connecting din connector on the top of the in-circuit emulator. <2> after connection, be sure to secure the emulation probe and in-circuit emulator with screws. figure 2-2. example of connecting ie-78000-r and emulation probe mounting screws emulation probe ie-78000-r (cnn note ) note this figure shows the case where the ie-78044-r-em is used as the emulation board. the connector to be connected differs depending on the emulation board. refer to the users manual of the in-circuit emulator or emulation board.
8 chapter 2 connection (3) connecting emulation probe and target system connect the emulation probe and target system in the following sequence: cautions 1. before connecting the emulation probe to the target system, be sure to connect the ground clip first. otherwise, the in-circuit emulator may be damaged by static electricity. 2. be sure to connect the pins in the correct direction. if they are connected in the wrong direction, the in-circuit emulator may be damaged. <1> turn off the power to the target system. <2> solder the conversion socket to the target system. use the following socket: ? EP-78024cw-r : shrink dip socket commercially available ? EP-78024gf-r : socket supplied as an accessory (ev-9200g-64) <3> connect the ground clip of the emulation probe to the ground (gnd) of the target system. <4> connect the emulation probe to the target system so that the position of the tip of the emulation probe comes to the position of pin 1 of the conversion socket solder onto the target system in step <2> above. figure 2-3. connecting EP-78024cw-r and target system 1 64 32 33 in-circuit emulator external sense clip ground clip 64-pin cw shrink dip socket (commercially available) target system

10 chapter 2 connection (4) connecting external sense clip (when external sense clip is used) the emulation probe is provided with an external sense clip that consists of eight clips and can trace the signals of the hardware on the target system in real time. because the external sense clip is directly connected to the input buffer hct244 in the in-circuit emulator, its input is ttl level. usually, the eight external sense clips are used as input signal lines. depending on the setting of the out command of the in-circuit emulator, however, the signal line of external sense clip 1 can be used to output a trigger signal to an external device when an event occurs (for details, refer to the manual of the in-circuit emulator). cautions 1. connect the external sense clips to the signal lines of ttl level. if they are connected to the other signal lines, the high and low levels of signals cannot be accurately detected. in addition, the sensors of the in-circuit emulator may be damaged depending on the voltage level. 2. when using external sense clip 1 as a trigger output line, make sure that external sense clip 1 is not connected to a signal output line. otherwise, malfunction may occur. h h
11 chapter 2 connection connect the external sense clip in the following sequence: <1> turn off the power to the target system and then to the in-circuit emulator. <2> mount a commercially available ic clip to the ic on the target system to be traced. <3> connect the external sense clip to the ic clip. <4> turn on the power to the in-circuit emulator and then to the target system. figure 2-5. connecting external sense clip ic ic clip target system external sense clip remark to connect the external sense clip, use an ic clip whenever possible, to prevent bad contact and improve operability.
12 chapter 2 connection 2.2 turning on/off power after connecting the emulation probe and target system, turn on the power. be sure to turn on or off the power in the sequence described below. caution be sure to turn on/off the power in the correct sequence; otherwise, the in-circuit emulator may be damaged. (1) power-on sequence <1> turn on power to the in-circuit emulator. <2> turn on power to the target system. (2) power-off sequence <1> turn off power to the target system. <2> turn off power to the in-circuit emulator.
