(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 oscillation circuit 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 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 oscillation circuit 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).

User's Manual U16226EJ3V0UM 19 CHAPTER 3 INSTALLATION (2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-780078-NS-EM1. (a) For main system clock 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 3-5.

Although the target device is a CMOS circuit, the IE-780078-NS-EM1's target interface circuit consists of emulation circuits such as an emulation CPU, 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 or output from the emulation CPU and PD780009 (2) Signals input or output from the emulation CPU and PD78F0078 (3) Other signals The IE-780078-NS-EM1's circuit is used as follows for signals listed in (1) to (3) above.

(1) In the external diffusion mode, the read data in address xx24H of the external memory becomes undefined. Measures: Use IE-78K0-NS control code L or later, or IE-78K0-NS-A control code E or later. When using products with control codes earlier than the above, set the PM4 register to 00H (port 4 set to output mode). (2) The value of the interrupt request flag register IF1L (FFE2H) after reset is 04H. Measures: 38 After reset, set the IF1L register to 00H.
