is intended for engineers who will use the IE-780338-NS-EM1 with the ie- 78k0-ns or ie-78k0-ns-a to perform system debugging. engineers who use this manual are expected to be thoroughly familiar with the target device?s functions and usage methods and to be knowledgeable about debugging. organization when using the IE-780338-NS-EM1, refer to not only this manual (supplied with the ie- 780338-ns-em1) but also the manual that is supplied with the ie-78k0-ns or ie-78k0- ns-a. the ie-78k0-ns used in combination with the ie-78k0-ns-pa is functionally equivalent to the ie-78k0-ns-a. therefore, as necessary, read ie-78k0-ns + ie-78k0-ns-pa for ie-78k0-ns-a in this document. ie-78k0-ns or ie-78k0-ns-a IE-780338-NS-EM1 user?s manual user?s manual ? basic specifications ? general ?

(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 device ? s internal oscillator is used. an example of the external circuit is shown in part (a) of figure 3-4. during emulation, the resonator that is mounted on the target system is not used. instead, the clock that is mounted on the emulation board connected 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 the target device ? s internal oscillator is not used. an example of the external circuit is shown in part (b) of figure 3-4. 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 directly connected to x1 (main system clock) and xt1 (subsystem clock). figure 3-4. 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 user ? s manual u16214ej1v0um 21 (1) clock that is already mounted on emulation board (a) for main system clock a crystal oscillator (x1) is already mounted on the emulation board. its frequency is 10.0 mhz. figure 3-5. when using clock that is already mounted on emulation board (main system clock) remark the clock that is supplied by the IE-780338-NS-EM1 ? s oscillator (encircled in the figure) is used.
