· 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# (pin 4) 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.
