(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 3-2. 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 device’s 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). Figure 3-2.

Its frequency is 5.0 MHz. Figure 3-3. When Using Clock That Is Already Mounted on Emulation Board IE-78K0-NS Target system IE-780233-NS-EM4 Mounted oscillator (to be used) Emulation probe Resonator (not used) Remark The clock that is supplied by the IE-780233-NS-EM4’s oscillator (encircled 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-780233-NS-EM4. Remove the crystal oscillator (X1) 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 3-4.

Remark When the IE-780233-NS-EM4 is shipped, the settings for “when using clock that is already mounted on emulation board” are preset. (1) When using clock that is already mounted on emulation board When the IE-780233-NS-EM4 is shipped, a 5.0 MHz crystal oscillator is already mounted in the IE-780233-NSEM4’s X1 socket. When using the factory-set mode settings, there is no need to make any other hardware settings.

Although the target device is a CMOS circuit, the IE-780233-NS-EM4’s target interface circuit consists of emulation circuits such as an emulation gate array, TTL, and CMOS-IC. When the IE system is connected with the target system for debugging, the IE system performs emulation so as to operate as the actual target device would operate in the target system. However, some minor differences exist since the operations are performed via the IE system’s emulation. (1) Signals input/output to/from the emulation gate array and µPD7880 (2) Signals input/output to/from the emulation gate array and µPD7881 (3) Other signals The IE-780233-NS-EM4’s circuit is used as follows for signals listed in (1) to (3) above.
