    (5 V). 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 TP1 terminal pin of the IE-789860-NS-EM1 (the same applies when the voltage is 5 V).

  • Page 22: Clock Settings

    CHAPTER 3 INSTALLATION 3.4 Clock Settings 3.4.1 Overview of clock settings The system clock 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 23 (2) Clock that is mounted by user The user can mount any clock supported by the set specifications on the IE-789860-NS-EM1. This feature is effective when debugging at a different frequency than the clock already mounted. Remove the crystal oscillator (X1) that is already mounted on the emulation board, and mount the parts board on which the resonator to be used is mounted or mount the oscillator to be used.

    The pulse that is supplied by the external clock on the target system (encircled in the figure) is used. 3.4.2 System clock settings Table 3-4 shows the system clock settings of the IE-789860-NS-EM1 when the system clocks in (1) to (3) are used. Table 3-4. Main System Clock Settings...
  • Page 25 CHAPTER 3 INSTALLATION (2) When using clock mounted by user Perform the settings described under either (a) or (b), 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).

(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).
