    CHAPTER 3 INSTALLATION This chapter describes methods for connecting the IE-789882-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.

    CHAPTER 3 INSTALLATION 3.3 Setting Power Supply Voltage of Target Interface In the IE system, emulation is possible with a voltage of the same level as the power supply voltage of the target system. When the target system is not connected, the IE system automatically operates with the emulator’s internal power supply (3.9 V).

  • Page 22: Clock Settings

    CHAPTER 3 INSTALLATION 3.4 Clock Settings 3.4.1 Overview of clock settings The main system clock and subsystem clock to be used during debugging can be selected from (1) and (1) and (2) below, respectively. (1) Clock that is already mounted on emulation board (2) Clock that is mounted by user 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 23 Clock oscillator or external clock (not used) Remark The clock that is supplied by the oscillator of the IE-789882-NS-EM1 (encircled in the figure) is used. (b) Subsystem clock A crystal oscillator (X2) is already mounted on the emulation board. Its frequency is 32.768 kHz.

  • Page 24: Main System Clock Settings

    CHAPTER 3 INSTALLATION (2) Clock that is mounted by user The user can mount any clock supported by the set specifications on the IE-789882-NS-EM1. This feature is effective when debugging at a different frequency than the clock already mounted. Subsystem clock Remove the crystal oscillator (X2) that is already mounted on the emulation board, and mount the crystal oscillator to be used.

  • Page 25: Subsystem Clock Setting

    NS-A. (1) When using clock that is already mounted on emulation board When the IE-789882-NS-EM1 is shipped, a 4.194304 MHz oscillator (X2) is already mounted on the IE-789882- NS-EM1. No settings are required on the integrated debugger (ID78K0S-NS). (2) When using clock mounted by user No settings are required on the integrated debugger (ID78K0S-NS).

Insert the crystal oscillator pins into the socket aligning the pins as shown in the figure below.

  • Page 27: Mask Option Settings

    INSTALLATION 3.5 Mask Option Settings By setting the DIP switch (SW1) in the IE-789882-NS-EM1, a 33 kΩ pull-up resistor can be connected to P50 to P53 by mask option. Use the mask option setting dialog box of the integrated debugger (ID78K0S-NS) to set the mask option. When reading a project file, however, setting is not required.

  • Page 28: External Trigger

    Connect a pull-up resistor on the target system because this is an open drain output. (2) EXTIN An event signal can be input from the EXTIN pin on the IE-789882-NS-EM1. Input a high-level pulse signal for 2 CPU operation clocks or more.
