(2) Manually switching the reset signal with jumper
Figure 5-5 illustrates the circuit connection for the case where the reset signal is switched using the jumper,
with or without MINICUBE2 connected. This connection is simple, but the jumper must be set manually.

(3) Resetting the target device by power-on clear (POC) only
Figure 5-6 illustrates the circuit connection for the case where the target device is only reset via POC without
using the reset pin. RESET_OUT is valid only when the debugger is running or during flash programming.
The operation is not guaranteed if the power to the target system is shut down during debugging. Note that
the POC function cannot be emulated.
