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 a reset input from the emulator can be accepted:
When a POR is in use
Vcc
User system
connector
MCU
Pin 13
RES# pin
When a POR is not in use
Vcc
User system
connector
User logic

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.
6. Refer to the hardware manual for the recommended capacitance of the capacitor that
is connected to the RES# pin.
7. Use of the internal oscillator circuit is available in the H8S/38524F. However, an
external clock input from pin OSC1 or OSC2 is necessary when the emulator is
connected.
