(1) clock that is already mounted on emulation board (2) clock that is mounted by user (3) external clock if the target system includes an in ternal clock, select either (1) clock that is already mounted on emulation board or (2) clock that is mounted by user . for an internal clock, a resonator is connected to the target device and the target device?s internal oscillation circ uit is used. an example of the external circuit is shown in part (a) of figure 3-2. during emulation, the resonator that is mounted on t he target system is not used. instead, the clock that is mounted on the emulation board c onnected to the ie-78k0-ns or ie-78k0-ns-a is used. if the target system includes an external clock, select (3) external clock . for an external clock, a clock signal is supplied from outside the target device and t he target device?s internal oscillation circuit is not used. an example of the exte rnal circuit is shown in part (b) of figure 3-2. caution the ie system will be hung-up if the system clo ck is not supplied normally . moreover, be sure to input a rectangular wave as the clock from the target. the ie system does not operate if the crystal resonator is dir ectly connected to x1. figure 3-2. external circuits used as system clock oscillation circuit (a) internal clock (b) external clock x2 x2 target device target device external clock x1 x1 chapter 3 installation user?s manual u16275ej3v0um 19 (1) clock that is already mounted on emulation board a crystal oscillator (umclk) is already mounted on the emulation board. its frequency is 8.38 mhz. figure 3-3. when using clock that is already mounted on emulation board ie-78k0-ns or ie-78k0-ns-a IE-780988-NS-EM4 resonator (not used) mounted oscillator (used) emulation probe target system remark the clock that is supplied by the oscillator of the IE-780988-NS-EM4 (encir cled in the figure) is used. (2) clock that is mounted by user the user is able to mount any clock supported by the set specifications on the IE-780988-NS-EM4. remove the crystal oscillator (umclk) that is alr eady mounted on the emulation board, and mount either the parts board on which the resonator to be used is mounted or an oscillator. this method is useful when using a different frequency from that of the pre-mounted clock. figure 3-4. when using user-mounted clock ie-78k0-ns or ie-78k0-ns-a IE-780988-NS-EM4 resonator (not used) target system emulation probe parts board + resonator or oscillator remark the clock that is supplied by the resonator or oscillator of the IE-780988-NS-EM4 (encircled in the figure) is used. chapter 3 installation user?s manual u16275ej3v0um 20 (3) external clock an external clock connected to the target system can be used via an emulation probe. figure 3-5. when using external clock ie-78k0-ns or ie-78k0-ns-a clock generator (used) emulation probe target system IE-780988-NS-EM4 (ie-78k0-ns-p01) remark the clock supplied by the target system?s clo ck generator (encircled in the figure) is used. 3.2.2 system clock settings table 3-1. system clock settings IE-780988-NS-EM4 frequency of system clock umclk socket cpu clock source selection (id78k0-ns) when using clock that is already mounted on emulation board 8.38 mhz oscillator used when using clock mounted by user oscillation circuit assembled by user internal when using external clock other than 8.38 mhz oscillator (not used) external caution when using an external clock, open the conf iguration dialog box when starting the integrated debugger (id78k0-ns) and select ?external? in the area (clock) for sel ecting the cpu?s clock source (this selects the user?s clock). remark when the IE-780988-NS-EM4 is shipped, the settings for ?when using clock that is already mounted on emulation board? are preset.
