PROTECT I
Host
processor
Reset protect pin. The R61509V enters a reset protect status by
fixing PROTECT to GND level disabling hardware reset. With
this, erroneous operations caused by noise are prevented.
Low: Hardware reset is disabled (Reset protect status)
High: Hardware reset is enabled. (Normal status)
