Remark
The characteristics of the dual-function pins are the same as those of the port pins unless otherwise
specified.
Note
For use as P07, use an inverter to input the reverse phase of P07 to the XT2 pin.
Caution
The oscillation circuit constants and oscillation voltage range indicate conditions for stable
oscillation. However, they do not guarantee accuracy of the oscillation frequency. If the
application circuit requires accuracy of the oscillation frequency, it is necessary to set the
oscillation frequency in the application circuit. For this, it is necessary to directly contact the
manufacturer of the resonator being used.
