    CHAPTER 3 INSTALLATION This chapter describes methods for connecting the IE-789801-NS-EM1 to the IE-78K0S-NS or IE-78K0S-NS-A, emulation probe, etc. Mode setting methods are also described. Caution Connecting or removing components to or from the target system, or making switch or other setting changes must be carried out after the power supply to both the IE system and the target system has been switched OFF.

  • Page 19: Connection

    CHAPTER 3 INSTALLATION 3.1 Connection (1) Connection with IE-78K0S-NS or IE-78K0S-NS-A main unit See the IE-78K0S-NS User’s Manual (U13549E) for a description of how to connect the IE-789801-NS-EM1 to Note the IE-78K0S-NS or IE-78K0S-NS-A Note When using the IE-78K0S-NS-A, refer to the IE-78K0S-NS-A User’s Manual (U15207E).

  • Page 20: Clock Settings

    CHAPTER 3 INSTALLATION 3.2 Clock Settings 3.2.1 Overview of clock settings The system clocks to be used during debugging can be selected from (1) to (3) below. (1) Clock that is already mounted on emulation board (2) Clock that is mounted by user (3) Pulse input from target system If the target system includes a clock oscillator, select either (1) Clock that is already mounted on emulation board or (2) Clock that is mounted by user.
  • Page 21 (2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-789801-NS-EM1. First mount the resonator on the parts board, then attach the parts board to the IE-789801-NS-EM1. This method is useful when using a different frequency from that of the pre-mounted clock.
  • Page 22 CHAPTER 3 INSTALLATION (3) Pulse input from target system An external clock connected to the target system can be used via an emulation probe. Figure 3-5. When Using an External Clock IE-78K0S-NS or IE-78K0S-NS-A Target system Emulation probe External clock (to be used) Remark The clock supplied by the target system’s external clock (encircled in the figure) is used.

  • Page 23: System Clock Settings

    (1) When using clock that is already mounted on emulation board When the IE-789801-NS-EM1 is shipped, a 6 MHz crystal oscillator is already mounted in the IE-789801-NS- EM1’s X1 socket. If the IE-789801-NS-EM1 is in the same state as when shipped, no hardware settings are required.
  • Page 24 CHAPTER 3 INSTALLATION (2) When using clock mounted by user The settings described under either (a) or (b) are required, depending on the type of clock to be used. When starting the integrated debugger (ID78K0S-NS), open the configuration dialog box and select “Internal” in the area (Clock) for selecting the CPU’s clock source (this selects the emulator’s internal clock).
  • Page 25 INSTALLATION <2> Prepare the IE-789801-NS-EM1. <3> Remove the crystal oscillator that is mounted in the IE-789801-NS-EM1’s socket (the socket marked as X1). <4> Connect the parts board (from <1> above) to the socket (X1) from which the crystal oscillator was removed.
  • Page 26 <Steps> <1> Prepare the IE-789801-NS-EM1. <2> Remove the crystal oscillator that is mounted in the IE-789801-NS-EM1’s socket (the socket marked as X1). <3> Connect the crystal oscillator (from <2> above) to the socket (X1) from which the parts board for external clock was removed.
  • Page 27 CHAPTER 3 INSTALLATION The above steps configure the following circuit and enable supply of the clock from the mounted resonator to the emulation device. IE-78K0S-NS or IE-78K0S-NS-A (Emulation device) Crystal oscillator 6 MHz HC157 Level shifter User’s Manual U13390EJ2V0UM...
  • Page 28 CHAPTER 3 INSTALLATION (3) When inputting pulse from target system No hardware settings are required for this situation. When starting the integrated debugger (ID78K0S-NS), open the configuration dialog box and select “External” in the area (Clock) for selecting the CPU’s clock source (this selects the user’s clock). The above steps configure the following circuit and enable supply of the clock on the target device to the emulation device.

  • Page 29: Setting Power Supply Voltage Of Target Interface

    When debugging with a voltage that is the same level as that of the target system, supply the same voltage as that of the target system to the TM1 terminal pin of the IE-789801-NS-EM1 (the same applies when the voltage is 5 V).

    3.5 Switch and Jumper Settings (1) Switch and jumper setting on IE-78K0S-NS When using the IE-789801-NS-EM1, set the switches and jumpers on the IE-78K0S-NS as shown in Table 3-2. For the position of the switches and jumpers, refer to the IE-78K0S-NS User’s Manual (U13549E).

  • Page 32: Differences Between Target Devices And Target Interface Circuits

    This chapter describes differences between the target device’s signal lines and the signal lines of the IE-789801- NS-EM1’s target interface circuit. Although the target device is a CMOS circuit, the IE-789801-NS-EM1’s target interface circuit consists of an emulation chip, TTL, CMOS-IC, and other components.
