(4) Resetting the target device by power-on clear (POC) only
Figure 4-21 illustrates the circuit connection for the case where the target device is only reset via POC without
using the reset pin. RESET_OUT becomes active when power is applied to MINICUBE2.
Even if power supply to the target system is turned off during debugging, pseudo POC function emulation is
<R> available because RESET_OUT becomes active. Note that the POC detection voltage is about 1 V higher
than that of the target device.
