This is the ground potential pin of A/D converter, P20 to P27. Even when the A/D converter is not used, always
This is the active-low system reset input pin.
When the external reset pin is not used, connect this pin directly to EV
When the external reset pin is used, design the circuit based on V
This is the pin for connecting regulator output (2.5 V) stabilization capacitance for internal operation. Connect this
Also, use a capacitor with good characteristics, since it is used to stabilize internal voltage.
Caution Keep the wiring length as short as possible for the broken-line part in the above figure.
