(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 internal 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 devices internal oscillator 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 the target system is not used. instead, the clock that is mounted on the emulation board installed for the ie-78k0-ns 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 the target devices internal oscillator is not used. an example of the external circuit is shown in part (b) of figure 3-2. caution the ie system will be hung-up if the main system clock 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 connected to x1 (main system clock) and xt1 (subsystem clock). figure 3-2. external circuits used as system clock oscillator (a) internal clock (b) external clock x2 or xt2 x2 or xt2 target device target device external clock x1 or xt1 x1 or xt1 chapter 3 installation users manual u14768ej1v0um00 22 (1) clock that is already mounted on emulation board (a) for main system clock a crystal oscillator (main clk) is already mounted on the emulation board. its frequency is 5.0 mhz. figure 3-3. when using clock that is already mounted on emulation board (main system clock) ie-78k0-ns IE-78048-NS-EM1 resonator (not used) mounted oscillator (to be used) emulation probe target system remark the clock that is supplied by the IE-78048-NS-EM1s oscillator (encircled in the figure) is used.

(a) for main system clock remove the crystal oscillator (main clk) that is already 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 3-5. when using user-mounted clock (main system clock) ie-78k0-ns IE-78048-NS-EM1 resonator (not used) target system emulation probe parts board + resonator or oscillator remark the clock that is supplied by the IE-78048-NS-EM1s resonator or oscillator (encircled in the figure) is used.
