See the IE-78K0-NS-A User's Manual (U14889E) for a description of how to connect the IE-780831-NS-EM4 to the IE-78K0-NS-P02 and IE-78K0-NS-A. (2) Connection with emulation probe See the IE-78K0-NS User's Manual (U13731E) or IE-78K0-NS-A User's Manual (U14889E) for a description of how to connect an emulation probe to the IE-780831-NS-EM4. On this board, connect the emulation probe to CN6. Caution Incorrect connection may damage the IE system.

(1) Clock that is mounted by user (2) External clock If the target system includes an internal clock, select (1) 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 (X1) that is to be mounted on the IE-78K0-NS-P02 is used. If the target system includes an external clock, select (2) 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 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. Figure 3-2. External Circuits Used as System Clock Oscillator (a) Internal clock (b) External clock Target device X1 Target device External clock X2 X1 X2 User's Manual U16239EJ2V0UM 19 CHAPTER 3 INSTALLATION (1) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-78K0-NS-P02. Remove the parts board (X1) that is already mounted on the IE-78K0-NS-P02, 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 3-3. When Using User-Mounted Clock (System Clock) IE-78K0-NS or IE-78K0-NS-A IE-78K0-NS-P02 Target system Parts board + resonator or oscillator Remark Emulation probe Resonator (not used) The clock that is supplied by the IE-78K0-NS-P02's resonator or oscillator (encircled in the figure) is used. (2) External clock An external clock connected to the target system can be used via an emulation probe. Figure 3-4.

Although the target device is a CMOS circuit, the IE-780831-NS-EM4'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 (PD7880) (2) Signals input or output from the emulation CPU (PD7881) (3) Other signals The circuits of the IE-78K0-NS-P02 and IE-780831-NS-EM4's are used as follows for signals listed in (1) to (3) above. (1) Signals input to or output from the emulation CPU (PD7880) See Figure 4-1 Equivalent Circuit of Emulation Circuit 1. * P27 to P20 * P36 to P30 * P75 to P70 * P87 to P80 * P97 to P90 * AVDD0 * AVREF0 * AVSS0 * AVREF1 * AVSS1 * RESET * X1 (2) Signals input to or output from the emulation CPU (PD7881) See Figure 4-2 Equivalent Circuit of Emulation Circuit 2. * P07 to P00 * P47 to P40 * P57 to P50 * P67 to P64 26 User's Manual U16239EJ2V0UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS (3) Other signals See Figure 4-3 Equivalent Circuit of Emulation Circuit 3. * VDD0, VDD1 * VSS0, VSS1 * VPP/TEST * X2 * C2TX * C2RX Figure 4-1.
