2.3.7 P137 (port 13)

P137 functions as an input port. P137 pin also functions as external interrupt request input.
(1) Port mode
P137 functions as an input port.
(2) Control mode
P137 functions as external interrupt request input.
(a) INTP0
This is an external interrupt request input pin for which the valid edge (rising edge, falling edge, or both rising and
falling edges) can be specified.

(2) V
SS
V is the ground potential pin. .

Remark Use bypass capacitors (about 0.1
wires at the shortest distance to V

2.3.9 RESET

This is the active-low system reset input pin.
When the external reset pin is not used, connect this pin directly or via a resistor to V
When the external reset pin is used, design the circuit based on V

2.3.10 REGC

This is the pin for connecting regulator output stabilization capacitance for internal operation. Connect this pin to V

via a capacitor (0.47 to 1
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.
