3. RES# of pin 4 of the H-UDI port connector is a signal line in which the emulator
outputs signals to the MCU. An AND operation must be performed between
RES# and the user system reset circuit for the signal line connected to the MCU.
RES# of pin 7 of the H-UDI port 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 H-UDI port
connector.

5. Ground pins 8 to 10, and 12 to 14 of the H-UDI port connector.
6. Pin 11 of the H-UDI port connector must be connected to the user system Vcc
(power supply). The amount of voltage permitted to input to the H-UDI port
connector must be within the guaranteed range of the microcomputer.
