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 system reset circuit must
be connected to 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 the RES# signal of
the MCU. The RES# must be pulled up before it is connected to pin 7 of the user
system connector.

Connect GND of pins 8 to 10, 12 to 14 of the user system connector to ground in the
user system.
5.
Connect Vcc, pin 11 of the user system connector, to the power supply (Vcc) in the
user system. The input voltage, Vcc, is within the range of guaranteed operation of
the microcomputer.
