Section 4 Example of Emulator Connection
3. The RES# pin is used by the emulator. Create the following circuit by connecting the
open-collector output buffer so that reset input can be accepted from the emulator.
Vcc
User system
connector
MCU
Pin 13
RES# pin

4. Connect Vss and Vcc with the Vss and Vcc of the MCU, respectively (within the
guaranteed range of the microcomputer).
When the power-supply mode is used, the power is supplied to the user system. Check
that the power consumption or voltage of the user system is within the available range
of E8a and avoid a problem such as closing of the power-supply circuit.
5. Connect nothing with N.C.
WARNING
In the power-supply mode, connect the emulator after
checking that the power-supply circuit on the user system is
not closed or the pin number assignments of the user system
connector is correct.
Failure to do so will result in a FIRE HAZARD and will
damage the host computer, the emulator, and the user
system.
2. Figure 4.5 shows the interface circuit in the E8a emulator. Use this figure as a
reference when determining the pull-up resistance value.
