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.

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.
