This is the A/D converter reference voltage input pin.
When A/D converter is not used, connect this pin to EV
Note Connect port 2 directly to EV
This is the A/D converter ground potential pin. Even when the A/D converter is not used, always use this pin with
This is the active-low system reset input pin.
This is the pin for connecting the capacitor for the regulator. When using the regulator, connect this pin to V
Caution A regulator cannot be used with (A1) grade products and (A2) grade products. Be sure to
These are the pins for connecting a resonator for X1 input clock oscillation.
When supplying an external clock, input a signal to the X1 pin and input the inverse signal to the X2 pin.
These are the pins for connecting a resonator for subsystem clock oscillation.
When supplying an external clock, input a signal to the XT1 pin and input the inverse signal to the XT2 pin.
