H8S, H8SX Family E10A-USB Emulator
3. RES(in)# of pin 4 of the user system connector is a signal line in which the emulator
outputs signals to the MCU. RES(in)# of pin 4 and the user logic reset circuit for the
signal line must be connected to pin RES# of the MCU as shown in figure 1.6.
RES(out)# of pin 7 of the user system connector is a signal line in which the emulator
monitors pin RES# of the MCU.
The RES# must be pulled up before it is connected to pin 7 of the user system
connector.

4. Ground pins 8, 9, 10, 12, 13, and 14 of the user system connector.
5. Pin 11 of the user system connector must be connected to the user system Vcc (power
supply). The amount of voltage permitted to input to the user system connector must
be within the guaranteed range of the MCU.
6. When the MCU in use is connected to the emulator, the pin functions listed below are
not available.
